Answer:
a. 3/6 or 1/2
A (even number) = 2, 4, 6
B (multiple of 2) = 2, 4, 6
A ∩ B = (2, 4, 6)
P (A U B) = P(A) + P(B) - P(A ∩ B)
P (A U B) = 3/6 + 3/6 - 3/6
P (A U B) = 3/6 or 1/2
b. 6/6 or 1
A (odd number) = 1, 3, 5
B (multiple of 2) = 2, 4, 6
P (A U B) = P(A) + P(B)
P (A U B) = 3/6 + 3/6
P (A U B) = 6/6 or 1
pls correct me of i'm wrong!
