How would you represent the area to the left of three in a probability statement?

Short Answer

Expert verified

The probability statement of the area to the left of three can be represented asP(x<3)

Step by step solution

01

Given Information 

Given in the question that, a graph

02

Explanation 

Consider the graph given in the question,

The area to the left of the normal probability represented as P(x<x)

The area to the right of the normal probability represented as P(x>x)

Therefore, we can represent the area to the left of three in a probability statement as P(x<3)
