Question

Find the probability of this event. Enter the answer as a fraction in simplest form, as a decimal to the nearest hundredth, and as a percent to the nearest whole number. You choose a movie CD at random from a case containing 4 comedy CDs, 5 science fiction CDs, and 7 adventure CDs. The CD is not a comedy.

Answer 1

0.75 is the probability of selecting a CD that is not comedy.

Explanation:

We are given the following in the question:

Number of comedy CD = 4

Number of science CD = 5

Number of adventure CD = 7

Total number of CD,n = 16

We have to find the probability for selecting a random CD that is not comedy.

Formula:

`\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}`

P( Non-Comedy CD) =

`=\frac{\text{n(Non-Comedy)}}{n}\\\\=(5+7)/(16) = (12)/(16)=(3)/(4)= 0.75 = 75\%`

Thus, 0.75 is the probability of selecting a CD that is not comedy.
