Probability Homework Practice

Question

A box of 50 candy bars contains 15 coffee Crisp, 15 Kit Kat, 10 aero, and 10 smarties. Two candy bars are chosen at random, one at a time without replacement. What is the probability that both candy bars are Kit Kat?

Choices:

9/98

2/15

3/35

9/100

Answer 1

P(2 Kit Kat candies) = P(KitKat₁)*P(KitKat₂)

=(15/50)*(14/49)

=210/2450

= 21/245

= 3/35
