Step-by-step explanation:
The area under the normal distribution to the left of z = 2.03 is shown in the attached image.
Given:
.
To find:
The value of
, rounding to the nearest thousandth.
Solution:
We know that,
![P(A\cup B)=P(A)+P(B)-P(A\cap B)](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3DP%28A%29%2BP%28B%29-P%28A%5Ccap%20B%29)
On substituting
, we get
![P(A\cup B)=0.44+0.6-0.394](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D0.44%2B0.6-0.394)
![P(A\cup B)=0.646](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D0.646)
Therefore, the value of
is 0.646.
