Question

Peter has a bag of candy containing 8 Swedish fish and 13 M&Ms. What is the probability that he eats a Swedish fish and than and M&M without putting it back

Answer 1

Answer: probability of 24.8% or 26/105

Explanation:

This situation resembles a permutation system.

First choice has the probability of 8/21

2nd choice has probability: 13/20 because the sample space was reduced from 21 to 20

Probability of choosing a swedish fish first and then a M&M is

(8/21)*(13/20) = (8*13) / (21*20)

= 26/105

= 24.8%
