Question

Suppose the sample space for a continuous random variable is 0 to 40. If thearea under the density curve for the variable from 0 to 6 is 0.15, what is thearea under the density curve from 6 to 40?A. 0.15B. 0.985C. 0.85D. 0.95

Answer 1

The area under the density curves for the continuous random variables always add up to unity.

Thus, the area under the density curve from 6 to 40 is ;

`1-0.15`

which is;

`0.85`
