Answer:
3/10
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
