Question

If P(AUB) =0.8 and P(ANB) = 0.3, then
find P(A) + P (B).​

Answer 1

Step-by-step explanation:

P(AUB)=P(A) +P(B) -P(ANB)

0.8+0.3=p(A)+p(B)

=1.1

Answer 2

The vaue of  P(A) + P (B) = 1.1

Step-by-step explanation:

Given by question:

P(A U B) = 0.8 and P(A ∪ B) = 0.3

To find, the vaue of  P(A) + P (B) = ?

We know that,

P(A U B)= P(A) + P(B) - P(A ∪ B)

⇒ 0.8 = P(A) + P(B)  - 0.3

⇒ P(A) + P(B) = 0.8 + 0.3

⇒ P(A) + P(B) = 1.1

∴ The vaue of  P(A) + P (B) = 1.1
