AveGali [126]
The probability is 19.88%.

This is a binomial distribution, because there are two outcomes, the events are independent of each other, and there is a fixed number of trials.  The binomial distribution is given by:

(_k^n)p^k(1-p)^{n-k}

For this, n is 18; k is 5; p is 0.25:
(_5^{18})(0.25)^5(1-0.25)^{18-5}&#10;\\&#10;\\=\frac{18!}{5!13!}(0.25)^5(0.75)^{13}&#10;\\&#10;\\=8568(0.25)^5(0.75)^{13}&#10;\\=0.1988=19.88%
