Determine if each curve (in orange) is a valid probability density function (i.e. if the total area under the function = 1)

Determine if each curve (in orange) is a valid probability density function (i.e. if the total area under the function = 1)

Shade the area corresponding to the probability listed, then find the probability.

$P\left(2<X<4\right)$

Shade the area corresponding to the probability listed, then find the probability.

$P\left(X<7.5\right)$
