Question

A spinner has 20 equally sized sections, 8 of which are yellow and 12 of which are blue. The spinner is spun and, at the same time, a fair coin is tossed. What is the probability that the spinner lands on blue and the coin is tails?

Answer 1

Answer:

3/10

Step-by-step explanation:

These two events are independent, so the overall probability is the product of the individual probabilities.

12 blue sections out of 20

p(blue) = 12/20 = 3/5

There is an equal probability of the coin landing on heads or tails.

p(tails) = 1/2

p(blue & tails) = 3/5 * 1/2 = 3/10

Answer 2

Answer:

3/10.

Step-by-step explanation:

Probability (A blue on the spinner) =  12/20 = 3/5.

Probability( tails) = 1/2.

The probability of a blue and tails = 3/5 * 1/2

=  3/10.
