Question

find the square of f. 0.2a-
0.3b​

Answer 1

Answer:

Answer

P(A)=0.5 and P(AB)=0.8

 When A and B are independent events, 

P(A∩B)=P(A)×P(B) 

⇒P(A)+P(B)−P(A∪B)=0.5×q

⇒0.5+q−0.8=0.5q

⇒0.5q=0.3

⇒q=0.6

When A and B are mutually exclusive events 

P(A∩B)=0 

P(A)+P(B)=P(A∪B)

0.5+p=0.8

⇒p=0.3

Hence the ratio of q and p is 2
