Given:
![P(A)=0.4, P(B)=0.7, P(A\text{ and }B)=0.3](https://tex.z-dn.net/?f=P%28A%29%3D0.4%2C%20P%28B%29%3D0.7%2C%20P%28A%5Ctext%7B%20and%20%7DB%29%3D0.3)
To find:
The value of
.
Solution:
We know that,
![P(A\text{ and }B)=P(A\cap B)](https://tex.z-dn.net/?f=P%28A%5Ctext%7B%20and%20%7DB%29%3DP%28A%5Ccap%20B%29)
![P(A\text{ or }B)=P(A\cup B)](https://tex.z-dn.net/?f=P%28A%5Ctext%7B%20or%20%7DB%29%3DP%28A%5Ccup%20B%29)
It means, we have
and we need to find the value of
.
![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)
![P(A\cup B)=0.4+0.7-0.3](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D0.4%2B0.7-0.3)
![P(A\cup B)=1.1-0.3](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D1.1-0.3)
![P(A\cup B)=0.8](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D0.8)
Therefore, the value of
is 0.8.
