Worksheets in this category help students to develop an understanding of probability, and also to calculate the probability of events using a range of different methods.

Worksheet Name	Files
Permutations and Combinations		Provides students with practice in finding the number of combinations and permutations of outcomes possible for a given number of trials - e.g. a team of 3 is to be formed from a group of 6 people. How many combinations are possible?
Odds		Looks at odds as used in gambling - e.g. horse racing. Requires students to calculate the amount returned for a winning bet at given odds.
Normal Probability		Students must use a calculator to find the mean and standard deviation of data which is normally distributed. Then, using given information, students calculate z-scores and determine the probabilities of an event occurring using the area under the curve of a standard normal table.
Expected Values		Provides students with practice in calculating the expected value of a trial in three practical situations - betting on a card game, insurance policy values and tossing a number of coins.
Normal Approximations to the Binomial		Students calculate the mean and standard deviation of outcomes in a binomial trial given the number of trials and the probability of success. Then, using given information, students calculate z-scores and determine probabilities from the area under the curve using a standard normal table.
Binomial Probability		Binomial experiments have two possible outcomes, success or failure. In this worksheet students calculate the probability of a certain number of successes in a given number of trials by applying the formula, and by using binomial distribution tables.
