Answer:

C. 1/9

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
