Question 4: You roll a fair die once. Define the events A = “the result is one of the numbers 1, 3, and 4”, B = “the result is one of the numbers 3, 4, 5, and 6”. • Are the events A and B independent? Jusitfy your answer using the definition of independence. • Are the events A and B independent? Jusitfy your answer using the definition of conditional probability.

Answer #1

P(A) = 3/6 = 1/2
P(B) = 4/6 = 2/3

P(A and B) = 2/6 = 1/3

P(A) * P(B) = 1/2 * 2/3 = 1/3

As P(A) * P(B) is equal to P(A and B), events A and B are independent.

    You roll a 6-sided die. The die has one to six spots on each side, with each count (1, 2, 3, 4, 5, or 6) appearing once. The die is fair: each side has an equal chance that it will be up when the die lands. What is the probability that you will roll a value greater than or equal to 2? Express your answer in decimal form to 3 decimal places.
