Question 1
If
P(
A) = .55,
P(
B ) = .4,
P(
A ∩ B) = .22, and
A and
B are independent events, find
P(
B).
◦ .4
◦ .88
◦ .22
◦ .55
Question 2
In a box of 50 markers, 30 markers are either red or black, 20 are missing their caps, and 12 markers are either red or black and are missing their caps. Are the events "red or black" and "missing cap" dependent or independent? Explain.
