The probability that a fair coin tossed 10 times will land heads up on all ten tosses is 1 out of _____. A. 2 B. 10 C. 2^10
C is the answer because there is a 1/2 chance for the first flip, 1/2 chance for the the second flip, and so on. The total probability will be 1/21/21/2, 10 times, to make 1/(2^10).
