Chapter 5: Q.5.1 (page 316)

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

Short Answer

Expert verified

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

The value of theP(2.5<x<7.5)will be0.625

Step by step solution

01

Given information

Given in the question that the function f(x)=18for 0鈮�x鈮�8

02

Solution

Here,

f(x)=18,鈥呪赌呪赌呪赌�0鈮�x鈮�80,鈥呪赌呪赌呪赌�otherwise

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

03

Solution

Again the required probability will be

P(2.5<x<7.5)=base脳height

=(7.5鈭�2.5)脳18

=5脳18

=0.625
