Question

You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent. If necessary round your answer to the nearest hundredth.

The probability of spinning an odd number, flipping heads, then spinning a yellow is ????

Answer 1

The answer to that problem is 1/9

Answer 2

probability = number of favourable outcomes / total number of outcomes

probability of spinning any number = 1/3

probability of tossing a coin = 1/2

probability of compound event = 1/3 * 1/2 * 1/3 = 1/18

probability of spinning an odd number, flipping heads, then spinning a yellow is = 2/3*1/2*1/3 = 1/9
