Given:

There is a density curve given in the question

Required:

We need to find for

[tex]\begin{gathered} P(X<1.6) \\ P(X>4.8) \end{gathered}[/tex]

Explanation:

Part a

We want to find P(X<1.6)

For this we just need to find the area below the curve until x=1.6, since we have a triangle we can do this:

[tex]P(X<1.6)=\frac{1}{2}*1.6*0.05=0.04[/tex]

Part b

For this case we want to find this probability:

P(X>4.8)

and we can complement rule and we got

[tex]P(X>4.8)=1-P(X<4.8)=1-\frac{1}{2}*4.8*0.15=0.64[/tex]

Final answer:

0.04

0.64
