The probability is 0.0008.

I used a binomial probability on this one, since there are two outcomes (either pass or fail); the events are independent (the probability of one person passing does not influence the probability of another passing); and there are a fixed number of trials (in this case, 20).

For binomial probabilities, we use the formula:
$_nC_k=p^k*(1-p)^{n-k}$

With our information, we have:

Find the volume of a cylinder with a diameter of 16 mm and a height of 5.7 mm

Mademuasel [1]

The volume formula for a cylinder is :
V= (pi)(r^2)(h)
So r= d/2 where d = 16mm so r= 8mm h is given as equaling 5.7mm
Now just plug it into the formula.
V=(pi)(8^2)(5.7) = 364.8 pi mm = 1146.053mm
