The odds are 1 in 2.

If she is a 41% shooter she will probably score a goal 41 times out of a hundred, but she will probably miss the other 59 times out of a hundred. So the probability that she will miss is 59 out of 100 = 59% = 0.59
As a coin has two sides, the odds are always 50-50.

75% is not correct. The odds of flipping 4 independent coins is the same as flipping one coin 4 times. The number of outcomes of 4 flips is 2^4 or 16. The number of ways to exactly get 3 Heads is 4 (THHH, HTHH, HHTH, HHHT) so your chance of flipping 3 heas is 4/16 or 25%. If you include the occurance that produced 4 of 4 Heads, then you get 5/16 or 31.25%.
If she is a 41% shooter she will probably score a goal 41 times out of a hundred, but she will probably miss the other 59 times out of a hundred. So the probability that she will miss is 59 out of 100 = 59% = 0.59
(1/5)*(1/4) = 1/20 the odds of a quarter falling out, multiplied by the odds of a quarter falling out after a single quarter has fallen out
As a coin has two sides, the odds are always 50-50.
1/4 you see if you flip two coins there's a better chance you'll get a head and a tail then any thing else. 2/4 you'll get a head and a tail, 1/4 you'll get two heads and 1/4 you'll get two tails.
3 out of 8
50/50 50/50? This is equal to 1 which would imply the probability of flipping a head is certain. Obviously not correct as the probability of flipping a head in a fair dice is 1/2 or 0.5

The odds of getting 3 heads in a toss of 3 coins is 1 in 8, or 0.125. Each coin is probabalistically unrelated to each other, so you simply multiply the odds for each coin. 1 in 2 times 1 in 2 times 1 in 2 is 1 in 8.
