PLEASE HELP URGENT!!!

Answer 1

0.70

Explanation:

According to the given question,

P(A) = 0.60

P(B) = 0.25

P(A and B) = 0.15

And we are asked to find P(A or B) ,

We know,

• P(A or B) = P(A) + P(B)-P(A and B)

Putting the values we get,

• P(A or B) = 0.60 + 0.25 - 0.15

• P(A or B) = 0.70

Thus option B is correct one.
