What is the probability of flipping a quarter three times and getting heads each time?
1/2 X 1/2 1/2 = 1/8
Similarly, the odds of flipping a quarter 25 times in a row and getting heads each time is:
1/2 X 1/2 X 1/2 X 1/2 X 1/2 X1/2 X 1/2 X 1/2 X 1/2 X 1/2 X1/2 X 1/2 X 1/2 X 1/2 X 1/2 X1/2 X 1/2 X 1/2 X 1/2 X 1/2 X1/2 X 1/2 X 1/2 X 1/2 X 1/2 = 33,554,432
