Question

You spin the spinner, flip, a coin, then spin the spinner again. Find the probability of the compound event. The probability of spinning an odd number, not flipping heads, then not spinning six is?

Answer 1

Answer:

20/81.

Step-by-step explanation:

There are 5 odd numbers in 1 to 9 and 4 even ones.

Prob(Odd number on first spin) = 5/9

Prob(Not flipping heads on second) = 1/2

Prob(Not spinning a 6 on third ) =  8/9

The compound probability is found by multiplying the above ( because each trial is independent of the others):

Answer = 5/9 * 1/2 * 8/9

= 40/162

= 20/81.
