Question

​

Answer 1

Answer:

Probability that both the parents will attend is 0.85

Step-by-step explanation:

Probability that mother will attend P(m)=0.7

Probability that father will attend P(f)=0.5

We know that

P(A∩B)=P(A)×P(B)

P(A∩B)=0.7 x 0.5=0.35

P(AUB)=P(A)+P(B)-P(A∩B)

P(AUB)=0.7+0.5-0.35

P(AUB)=0.85
