For each birth, you have two choices - either a boy or a girl. Then, the probability for a certain birth to obtain a choice is ½.
Using Binomial Theorem, we have (10 choose 8)(½)8(½)² = 45/1024.

If probability of male birth is 0.52 What is the probability that there will be more girls than boys in 100 births?
0.48
What is the probability of exactly 7 boys in 10 births when the birth of any child does not affect the probability of the gender of any other children?
This is a Binomial Probability; p=0.5, n=10 & x=7. Since you want the probability of exactly 7, in the related link calculator, after placing in the above values, P(x=7) = 0.1172 or 11.72%.

Probabilty of having 12 boys and 1 girl?
Assuming the probability of having a boy is 1/2, and that the probabilities are independent: Probability of 1 girl and 12 boys = (1/2)13 * 13 = 0.001587..., which is around 1/630
