Question 2 of 10You roll a 6-sided die with faces numbered 1 through 6, and toss a coin. What is the probability of rolling a 3 or getting heads?A.B.C.D.

3 pointsA fair die is rolled twice and a fair coin is tossed twice. Define eventsA : A three appear on the die twice.B : A head appear on the coin twice.Find the value of P(A ∩ B).1/61/721/121/144
