Question

Harley randomly selects a chocolate from a box containing

15 milk chocolates and 5 white chocolates. If he gets a white
chocolate, he puts it back. If he gets a milk chocolate, he
eats it.
Find the pr that he selects 2 white chocolates in a row?

Answer 1

Answer: Since Harley puts the white chocolate back after selecting it, each selection is independent and the probability of selecting a white chocolate is 5/20=1/4.

The probability of selecting 2 white chocolates in a row is given by:

P(white and white) = P(white) * P(white)

= 1/4 * 1/4

= 1/16

Therefore, the probability that Harley selects 2 white chocolates in a row is 1/16.
