Specific statistical methods have helped the civilization to identify, study, and solve a variety of problems. Statistics help people make effective decisions in uncertain situations.
Probability is used to illustrate events that do not take place with certainty. Statistics reveals the concepts of association between two variables, probability, random sampling, and estimation. People in various occupations tend to apply statistics. Health specialists use statistical methods to resolve whether a particular drug or procedure is useful in the treatment of medical issues.
Weather forecasters use statistics to more precisely predict the weather. Engineers use statistics to scale standards for product safety, security and quality. Scientists employ statistical methods to conduct efficient experiments. Economists apply statistical techniques in foreseeing future economic tendencies. Questions in statistics and probability can sometimes be pretty tricky and acquire a lot of time, knowledge and effort.
It also sometimes occurs that the assignments do not always correspond with the knowledge and information given to the students within the course. Can you guess what happens when we try to get three events to happen? The probability is even lower Try to figure out the probability of getting three heads in a row. Practice using the steps to solve the following probability problems.
Refer back to the previous examples for help. If you get stuck, take a deep breath and start over with step 1. Keep in mind that these are word problems. List the given and needed information before attempting to solve the problem. That way you won't miss important details. There are two tokens in a bag, one is white and the other is blue.
What is the probability that you will take out the blue token? Your mother makes turkey on weekdays and beef on the weekends. You don't know what day it is. What is the probability that you will have turkey for dinner? There are two puppies at Shelly's house. Shelly hopes that the puppies are girls. What are the chances that one puppy is a girl? What are the chances that both puppies are girls? There are two different events, and you can only have white or blue--just like the coin can only show heads or tails.
This is a tricky problem because of the wording. You know that your mother makes turkey on 5 days, and beef on 2. Even though there are only two options, it is easier to solve the probability problem by keeping the week divided into equal pieces days. Turkey is dinner 5 out of 7 days.
So the probability of having turkey is 5: This was a two-part question. First you want to know what the chances are of one puppy being a girl. Even though there are two puppies, we are only thinking about one right now. That one puppy can either be a boy or a girl. That makes two possible events, with one outcome; so there is a 1: The second puppy has the same chance.
So using the steps for solving a joint probability there is 1: Another way to look at this is to write out the possible gender combinations. If you know that one puppy is a girl. What is the probability that they are both girls? The answer is not 1: Problems With Probability Learning how to solve probability problems can be tricky for many people. Events may be any occurence such as: Going to the doctor, Standing on a yellow brick or Seeing a monkey.
The Coin Toss When you flip a coin, there are two events can occur: The coin could land on heads or the coin could land on tails.
Count the number of possible events. Heads Count the number of chances that heads can occur out of the possible events 1 Write the number of chances heads could occur over the number of possible events in a ratio. Want to Test the Probability? Coin Toss Experiment Materials Needed: A paper, a pencil and a quarter Toss the quarter times and tally the number of heads and tails. Count the number of tallies for each event. The number of each event occurring will be very close to The more you toss the quarter, the more likely you are to have an even distribution.
There are 6 sides to the dice. So there are 6 possible events. Decide which event you are examining for probability. The problem let's us know we are trying to roll a four. Count the number of chances that heads can occur out of the possible events.
There is only one side of the die that has 4 dots, so there is only 1 chance to roll a four out of 6 total chances. Write the number of chances heads could occur over the number of possible events in a ratio. There are four possible options. We are figuring out the probability of landing on white. Two out of four options are white So the probability of landing on white is 1: Did you think it was 2: Always remember to simplify your ratios!
Joint Probability There are many different types of probability that describe the circumstances, the variables, that impact a certain event. Write down the probability of the first event. Just follow the four-step process we used earlier. Write down the probability of the second event. Multiply the two ratios. Practice Problems Practice using the steps to solve the following probability problems. Coin Toss Problem 7: Practice Problem Answers Answer 6: Your teachers are there to help you out.

Oct 02, · What Could be the outcome? I know what a tree Diagram is but this Problem confuses me? A)A box contains three white balls and two red balls. A ball is drawn at random from the box and not replaced. Then a second ball is drawn from the box. Draw a tree diagram for this experiment and find the probability that the two balls are of different filefreevd.tk: Resolved.
Probability Math Help Probability Math is the study of calculating the chance of future events occurring. Finding the probability of events occurring may be exact values such as the probability of a rolled die landing on 1 or might be only an estimate from repeated trials of an experiment. The probability of an outcome is determined by how likely it is to happen, in a range between 0, for impossible, and 1, for certain, in a decimal or fraction.
