For any continuous probability distribution, the total area under the curve indicating the probability density function must be 1.

\mathbb P(X\le a)=0.75 is saying that the area to the left of x=a is 0.75. This area is also that of a rectangle.

The height of this rectangle is 0.25, and \dfrac{0.75}{0.25}=3, which means the width is 3. Since 4 - 1 = 3, it must be that a=4.
