Question

You spin the spinner, flip a coin, then spin the spinner again. Find the probability of spinning an odd number, flipping heads, then spinning another odd number. Write your answer as a fraction in simplest form.

Answer 1

Multiply the three probabilities in order to get the compound probability:

P(odd number)= 5/10 because 5 numbers out of ten are odd
P(heads)= 1/2 because there is an equal to chance to get heads or tails
P(odd number)= same as before, 5/10 (independent events)

5/10*1/2*5/10

1/2*1/2*1/2= 1/8

Final answer: 1/8
