Question

You have a set of 10 cards numbered one to 10 you choose a card at random event A is choosing a number less than seven. event B is choosing an odd number. calculate the probability

Answer 1

• 12) P(A ∩ B)

Explanation:

Event A:

• A ∈ {1, 2, 3, 4, 5, 6}

Event B:

• B ∈ {1, 3, 5, 7, 9}

Both events result in the set:

• A ∩ B = {1, 3, 5}

Required probability is:

• P(A ∩ B) = 3/10

Correct choice is 12
