What is the probability when two people alternately are picking first from a class with 12 girls and 13 boys and then from a class with 10 boys and 11 girls that the first will pick two girls first?
The fact that the two people are picking alternately first from one class and then from the second means that the first picker always has first selection from whoever is remaining in each class; thus for the first picker: pr(1st girl) = 12/(12+13) = 12/25 Pr(2nd girl) = 11/(11+10) = 11/21 → Pr(two girls picked) = pr(1st girl) × pr(2nd girl) = 12/25×11/21 = 44/175
What is the describing of the complementary event and find its probability?
Suppose there is an event A and the probability of A happening is Pr(A). Then the complementary event is that A does not happen or that "not-A" happens: this is often denoted by A'.Then Pr(A') = 1 - Pr(A).Suppose there is an event A and the probability of A happening is Pr(A).

What is the difference between the multiplication rule for independent versus dependent events?
Given two events, A and B, Pr(A and B) = Pr(A)*Pr(B) if A and B are independent and Pr(A and B) = Pr(A | B)*Pr(B) if they are not.
A spinner is divided into 10 equal section numbered 1 through 10. If the arrow is spun twice what is the probability the first number will be 2 and the second number will be 4?
pr(2 then 4) = pr(2) × pr(4) = 1/10 × 1/10 = 1/100
What is the probability of obtaining exactly three heads in four flips of a coin given that at least two are heads?
Pr(3H given >= 2H) = Pr(3H and >= 2H)/Pr(>=2H) = Pr(3H)/Pr(>=2H) = (1/4)/(11/16) = 4/11.

What is the probability of obtaining 4 ones in a row when rolling a fair six sided die?
The following is the probability of obtaining 4 ones IN THE FIRST FOUR rolls of a fair die. Pr(4 1's) = Pr(1)*Pr(1)*Pr(1)*Pr(1) since the events are independent. Pr(4 1's) = Pr(1)4 = (1/6)4 = 1/1296 = 0.000772

If a single die is rolled twice What is the probability of getting a 3 the first time and a 5 the second time?
Pr(3 the first time) = 1/6 or 16.67% Pr(5 the second time) = 1/6 or 16.67% Pr(3 the first time AND 5 the second time) = 1/6*1/6 = 1/36 = 2.778%
