Spins a fair spinner numbered 1 - 5 and flips a fair coin. What is the probability of obtaining a factor of 15 and a tail?

3/10

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that the fair spinner is numbered 1 - 5, the factors of 15 there are 1, 3 and 5 hence the probability of obtaining a factor of 15

= 3/5

The probability of obtaining a tail from the flip of a coin

= 1/2

Hence the probability of obtaining a factor of 15 and a tail

= 3/5 * 1/2

= 3/10

2nd one in the first row is correct
