Short Answer

Expert verified

The probability statement of the area to the left of one can be represented as P(x<1)

Step by step solution

01

Given Information 

Given in the question that a diagram

We have to represent the area to the left of one in a probability statement

02

Explanation

Let's consider the graph:

The left side area in the given graph shows the area to the left of x.

This area is represented by the probability P(X<x)
