Answer:Astronomers estimate the age of the universe in two ways: 1) by looking for the oldest stars; and 2) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang; just as crime detectives can trace the origin of a bullet from the holes in a wall.

Darina [25.2K]

Answer:

A and B are not independent

Explanation:

Given

P(A) = .3,

P(B) = .5

P(A\ n\ B) = .25

Required

Determine if A and B are independent

If A and B are independent, then:

P(A\ n\ B) = P(A) * P(B)

Substitute values for P(A) and P(B)

P(A\ n\ B) = .3 * .5

P(A\ n\ B) = .15

The calculated value of P(A n B) and the given value of P(A n B) are not equal.

i.e.

.15 \ne .25

<em>Hence, A and B are not independent</em>
