A binomial event has n = 20 trials. The probability of success for each trial is 0.20. Let x be the number of successes of the event during the 20 trials. What is the probability that x is at least 13?

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
