Suppose a and b are dependent events. if p(a|b)=0.55 and p(b)=0.2 , what is p(aub) ?

Hence,

P(A∪B)=0.89

Step-by-step explanation:

As we are given that:

A and B are dependent events.

If P(A|B)=0.55 and P(B)=0.2 .

AS we know that:

P(A)+P(B)=1

⇒ P(A)+0.2=1

⇒ P(A)=1-0.2

⇒ P(A)=0.8.

Also we know that:

Hence,

Hence,

P(A∪B)=0.89

step-by-step explanation:

the answer is 128
