Step-by-step explanation:
a²+b²=c²
19 x 19 = 361

The binomial probability is determined by the formula

Here, we will assume that finding the flaw is the "success" of the trial hence the following given

Finding the probability of one flawed scarf

Finding the probability of no flawed scarves

Finding the probability of more then three flawed scarves
