Question

*PLEASE help*
P(A)= 98%, find p(not A)

Answer 1

`P(A')=1-P(A)=100\%-98\%=2\%`

Answer 2

Hi there!

Given P(A) = 98%

To find P(not A) we must first convert P(A) into a decimal. To find 98% as a decimal we only need to divide by 100.

`98\% = 98 / 100 = 0.98`

Now we know the following:
P(A) = 0.98. To find P(not A) we need to subtract P(A) from 1.

P(not A) =
`1 - P(A)`
P(not A) =
`1 - 0.98 = 0.02`

Change into a percentage by multiplying the decimal by 100.
P(not A) = P(A') =
`0.02 * 100 = 2\%`

Hope this helps you!
