How to solve this problem with steps? That answer was not correct

A new stain removal product claims to completely remove the stains on 95 percent of all stained garments. Assume that the product will be tested on 20 randomly selected stained garments, and let x denote the number of these garments from which the stains will be completely removed. Find P(x s 18) if the stain removal product's claim is correct. If x actually turns out to be 18, what do you think of the claim? (Do not round interim calculations and round your final answer to 4 decimal places.) P(x S 18) 0.7547 There is no evidence against it
