Question

A survey revealed that 35% of people are entertained by reading books, 28% by watching TV, and 10% are entertained by both books and TV. What is the probability that a person will be entertained through neither a book nor TV?

Answer 1

neither A is the complementary of A (1-A)
or is Union
try to write that symbolically

Answer 2

1-P(A U B)’

Answer 3

A= 35%
B=28%
P(A ∩ B)= 10%
P(A ∪ B) = 73%

Answer 4

P(A ∪ B) how do u find that?

Answer 5

P is the symbol for probability

Answer 6

So it reads the probability of the union of A and B I made up A and B, A is Books And B is TV

Answer 7

P(A ∪ B) = P(A)+P(B)-P(A ∩ B)

Answer 8

So is that the formula for neither or?

Answer 9

no this for the union, so then find 1- P(A ∪ B)

Answer 10

that gives me 63%

Answer 11

sorry 53%

Answer 12

1-0.53
