The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is a divisor of 5". Find P(not A).

Answer explanation

A:divisor of 5

A: {1, 5}

not A: {2, 3, 4, 6, 7, 8}

P(not A) = 0.2 + 0.04 + 0.13 + 0.19 + 0.04 + 0.05

P(not A) = 0.65

The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is a divisor of 4". Let B be the event "the outcome is divisor of 3". Find P(A and B).

Answer explanation

A: divisor of 4

A: {1, 2, 4}

B: divisor of 3

B: {1, 3}

A and B = {1}

P(A and B) = 0.08
