jimthompson5910 (jim_thompson5910):
If the probability of success is 1/4, then the probability of failur is 1 - (1/4) = 4/4 - 1/4 = 3/4
jimthompson5910 (jim_thompson5910):
Since we have five trials with no successes, ie 5 failures, this means that the probability of this happening is (3/4)*(3/4)*(3/4)*(3/4)*(3/4) I'll let you compute that. Notice how there are 5 copies of 3/4
jimthompson5910 (jim_thompson5910):
as a shortcut, you can compute (3/4)^5
