What is the probability of having 3 boys for 4 kids?
Assuming probability of having a boy is P(B) = 1/2, and of having a girl is P(G) = 1/2,
the probability of having 3 boys for 4 kids (with out regard to the girl to be the first,
second, third or fourth kid) is;
P(3B1G) = 4C3 [P(B)]4 = 4 (1/2)4 = 0.250 = 25%
The factor 4 comes because there are 4 possibilities for the order in which the girl can
come out.

Why does the effect-size calculation use standard deviation rather than standard error?
The goal is to disregard the influence of sample size. When calculating Cohen's d, we use the standard deviation in teh denominator, not the standard error.

Three ways out of 36 possible combinations = 3/36 = 1/12
What is the probability of getting a total of 7 whilst rolling 2 ordinary dices?
Your total possible number of combinations: 62 = 36
Combinations that can add up to 7:
1-6
2-5
3-4
4-3
5-2
6-1
So your odds of rolling a seven would be 6/36, or 1/6.
