So this is going to be 1, this is going to be equal to 1, let me do it in that same color of green. This is going to be equal to 1 minus, our numerator, you just have 1 times itself 10 times, so that's 1. And then on the denominator, you have 2 times 2 is 4, 4 times 2 is 8, 16, 32, 64, 128, 256, 512, 1,024. This is the same exact same thing as 1 is 1024 over 1024 minus 1 over 1024, which is equal to 1023, or 1,023, over 1,024, we have a common denominator here, so 1,000, doing that same blue, over 1,000 and 1,024. So if you flip a coin 10 times in a row, a fair coin, you're probability of getting at least one heads in that 10 flips is pretty high. It's 1,023 over 1,024, and you can get a calculator out to figure that out in terms of a percentage. Actually, let me just do that just for fun.
