Question

Mr. Lance keeps a jar of candy on his desk for students to pick from when they do well on a test. The jar contains 5 Snickers, 2 Butterfingers, 4 Almond Joys and 3 Milky Ways. If two students get to pick candy from the jar, what is the probability that the first student picks a Snickers and then the second student also picks a Snickers?

10/91

25/182

25/91

10/98

Answer 1

it equals 10/91 whoop whoop

Answer 2

Probability = number of outcomes / total number of sample space

Number of Snickers = 5
Total number of candy = 5 + 2 + 4 + 3 = 14

Probabilty that the first student picks a Snickers = 5/14

After picking by the first student, the number of snickers reduces to 4 and the total number of candies reduces to 13

Probability that the second student also picks a Snicker = 4/13

Therefore, required probability is 5/14 x 4/13 = 20/182 = 10/91
