Question

Can anyone help me on the last question?

Answer 1

0.7

Explanation:

A' is everything what is not A

So:

A' = {9, 10, 11, 12, 13, 15, 16}

Number of ways it can happen: |A'| = 7

Total number of outcomes: |Ω| = 10

Probability of an event happening:

`\bold{P(A')=(|A'|)/(|\Omega|)=\frac7{10}=0.7}`
