Question

Example:
If the sample space is S, S = C1 U C2, if P(C1) = 0.8, PC2) = 0.5 then find PGC2).​

Answer 1

Answer:

If the sample space is C = C1 ∪C2 and if P(C1) = 0.8 and P(C2) = 0.5, find P(C1 ∩ C2).

Answer 2

0.3

We know that P(S) = 1

⇒ P(C1, UC2,)=1

By addition law of probability

⇒ P(C₁ C₂)=P(C₁) +P(C) - P(C, C₂)

⇒1=0.8+0.5-P(C, C₂)

⇒P(C₁ C₂) 1.3-1=0.3
