A. If it is the first pick, it doesn't matter what the subsequent picks are, 10/30.

B. More than two women means 3, 4 or 5 women.

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

For 5 women, P = 5/30 * 4/29 * 3/28 * 2/27 * 1/26 = ?

For 4 women, P = 5/30 * 4/29 * 3/28 * 2/27 * 25/26 = ?

For 3 women, P = ?

Either-or probabilities are found by adding the individual probabilities.

C. P = 1/30 * 1/29 = ?

2B : Hypergyometric: N=30, G=5, n=5, g>=3

Value: 2.193%

2C : Again Hypergeometry

2 Good items (Tom & Jerry).

So in 2C, N=30, G=2, n=5, g=2
Probability = 0.0299 = 0.023

LOL. Yes. You guys really know your probability. And what are you going to do with your certificate? Use it as toilet paper? Well that's about all it's good for. You've made sure of that.
