45 sequences. Make it easier and think what are the 2 tail flips. They are: 1-2; 1-3;1-4...1-10. That is 9 sequences starting with 1. There are 9 sequences starting with 2, 9 starting with 3, etc, up to 10. That makes 90 sequences, but since 1-2 is the same as 2-1, ie order doesn't matter, divide that in half to get 45.

Toss a fair coin 10 times. If you know that at least 7 heads are tossed, what is the probability that your first toss is heads?
Knowing the results in advance, there is a 7/10 chance that the first toss is heads. In this case "seven out of ten" is quite literal. The first toss is one of the 10, and 7 of them came up heads, so 7/10 is the chance that this particular one is one of the heads.

If you flipped a coin ten times what is the probability you would get five heads?
We need to calculate two things:How many possible possible series of 10 coin flips are there? As we flip 10 times and each time we can have either heads or tails we have 2 by the power of ten possibilities, or a total of 1024 unique possible series.Now, how many of those series have exactly five heads and five tails? Lets assume we have ten "pre filipped" coins at hand - 5 tails and 5 heads. How many possible combinations are there. Well, if they were all different, you would have 10! (10 factorial = 10*9*8*7*6*5*4*3*2*1) possibilities.How ever, the 5 heads are identical and so are the 5 tails, so if I interchange the locations of two coins that are both heads for example I still get the exact same series. There are 5! possible heads combinations, and 5! tails combinations.Thus, the total number of unique combinations is 10!/(5!*5!) which happens to be 252.So, out of 1024 possible series, 252 contain exactly 5 heads.The probability thus is 252/1024=0.24609375 (roughly 25%)
