Question
Toss a fair coin ten times. Find the probabiltiy of getting heads at least once. Can anyone help me to see how this works out?

That is 1 minus the probability of getting tails every time.
Why? Because either you get tails every time, or you get at least one heads.
That would be 1 - (1/2)^10 = 0.999023
