Question

check my answer ?

The graph shows a probability distribution.


What is P(1.5≤X≤3)?

Enter your answer, as a decimal, in the box.
P(1.5≤X≤3)
= 4.5

Answer 1

The required probability is the ratio of the shaded area to the total area of the distribution:
\[\large P(1.5 \le X \le 3)=\frac{3-1.5}{4-1}=?\]
