Short Answer

Consider the function f(x)=18 for 0 x 8. Draw the graph of f(x) and find P(2.5 < x < 7.5).

The graph of the P(2.5<x<7.5) is

The value of the P(2.5<x<7.5) will be 0.625

See the step by step solution

Step by Step Solution

Step 1: Given information

Given in the question that the function f(x)=18 for 0x8

Step 2: Solution


f(x)=18,    0x80,     otherwise

The graph of f(x) for P(2.5<x<7.5) is drawn below,

Step 4: Solution

Again the required probability will be

P(2.5<x<7.5)= base × height
