Calculate probabilities from multivariate tables.

Speeding violation in the last year No speeding violation in the last year total Car phone user 25 280 305 Not a car phone user 45 405 450 total 70 685 755 What is the probability of a person not being a car phone user? What is the probability of a person having a speeding violation in the last year? What is the probability a person who is a car phone user has had a speeding violation in the last year? What is the probability that a person has had a speeding violation in the last year given that they are a car phone user? Given that a person has not had a speeding violation in the last year, what is the probability they are a car phone user?

Speeding violation in the last year No speeding violation in the last year total Car phone user 25 280 305 Not a car phone user 45 405 450 total 70 685 755 450/755 What is the probability of a person not being a car phone user? What is the probability of a person having a speeding violation in the last year? 70/755 What is the probability a person who is a car phone user has had a 25/305 speeding violation in the last year? What is the probability that a person has had a speeding violation in the last year given that they are a car phone user? 25/305 What is the probability that given a person has not had a speeding 280/685 violation in the last year, they are a car phone user?

Calculating Probabilities from Practical Information 65 people were surveyed. 23 were vegetarian and 42 were not. 26 were female and 39 were male. Not Vegetarian Total Vegetarian Females Males Total: 11 27 23 39 65 Copy the table, fill in the gaps then Calculate the probability that a randomly chosen… (a) Person was vegetarian (g) Female was vegetarian (b) Person was not vegetarian (h) Vegetarian was female (c) Person was female (d) Person was male (e) Person was a male vegetarian (f) Female was not vegetarian
