Andy spins a fair spinner numbered 1 - 5 and rolls a fair dice. What is the probability of obtaining a multiple of 4 and a factor of 15?

The probability of getting a multiple of 4 AND a factor of 15 (1,3,5,15)   is ZERO as no factor of 15 is a multiple of 4.

 

Probability of a multiple of 4  (4 or 8 ) is  7/30

 

Probability of a FACTOR of 15 (1 3 5 15)  is 6/30
