Answer:
The average number of points this player will get in 100 one-and-one free throw situations is 70.
Step-by-step explanation:
For each free throw, there are only two possible outcomes. Either the player makes it, or he does not. The probability of the player making a free throw is independent of other free throws. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

70% free throw percentage.
This means that 
What is the average number of points this player will get in 100 one-and-one free throw situations?
This is E(X) when n = 100. So

The average number of points this player will get in 100 one-and-one free throw situations is 70.
All together, the two girls ate 8/15 of a pizza. you mulitply your fractions out of equal denominaters and get that.
Check the picture below.
now, to get how much is the area of the tiled section, we simply get the area of the whole pool, 53x26, which includes the tiles, and then subtract the area without the tile, the rectangle in the middle, and what's leftover, is the area of the tiled area.
