Find the probability of randomly selecting a student who spent the money, given that the sludent was givein four quaners The probability is 59 (Round to three decimal places as needed.) b. Find the probability of randomly The probability is 267 Round to three decimal places as needed) e. What do the preceding resuts suggest selecting a student whio spent the money, given that the student was given a sExplanation / Answer
From the given data
a) P(a student who spent the money / student was four quarters)
= P( a student who spent the money and student was four quarters) / P(student was four quarters)
= (25/87) / (42/87) = 25/42 = 0.59524
b) P(a student who spent the money / student was $1 bill)
= P( a student who spent the money and student was $1 bill) / P(student was 1$ bill)
= (12/87) / (45/87) = 12/45 = 0.2667
c) Correct answer: option (A)
