Question

Harold randomly selected one square tile and one round tile from the sets shown below. What is the probability that Harold selected a pink square tile, and either a red or a blue round tile ?
A. 3/5
B. 14/60
C. 1/9
D. 4/45

Answer 1

Answer:

  C.  1/9

Step-by-step explanation:

Assuming the selections are independent, their joint probability is the product of the probabilities of the individual events.

  P(pink square) = (# pink squares)/(# squares) = 16/60 = 4/15

  P(red or blue round) = (#red or blue rounds)/(# rounds) = 15/36

Then the joint probability is ...

  P(defined event) = (4/15)(15/36) = 4/36 = 1/9
