Question

About 51% of U.S. college students are below 25 years old. About 24% of U.S. college students are above 34 years old. What is the probability that a U.S. college student chosen at random is below 25 or above 34 years?0.760.740.751.75

Answer 1

0.75

Step-by-step explanation

The probability that a U.S college student chosen at random is below 25 years is:

`\begin{gathered} =51\text{ \%} \\ =(51)/(100)=0.51 \end{gathered}`

The probability that a U.S college student chosen at random is above 34 years is

Now, by addition law of probability, the probability that a U.S college student chosen at random is below 25 or above 34 years would be

`\begin{gathered} 0.51+0.24 \\ =0.75 \end{gathered}`
