Question

Suppose the sample space for a continuous random variable is 0 to 80. If the area under the density curve for the variable from 0 to 5 is 0.0625, what is the area under the density curve from 5 to 80?
A. 0.9375
B. 0.975
C. 0.375
D. 0.99375

Answer 1

Hello,

Area under the curve is 1.

So p(x>5)=1-p(x<5)=1-0.0625=0.9375

Answer A
