	SUV	sports car	totals
male	21	39	60
female	135	45	180
totals	156	84	240

a. What is the probability that the chosen participant is female?

b. What is the probability that the chosen participant prefers a sports car?

c. Whatistheprobabilitythatthechosenparticipantisamaleand prefers a SUV?

d. What is the probability that the chosen participant is either a male or prefers a SUV?

Solutions

Expert Solution

Let , S be the Sample space . Therefore , n(S)=240

a. Let , F be the event that the participant is female

Therefore ,

b. Let , A be the event that the participants prefers a sports car

Therefore ,

c. Let , M be the event that the participant is male and B be the event that the participant prefers a SUV

Therefore ,

d. Let , M be the event that the participant is male and B be the event that the participant prefers a SUV

Therefore ,
