3. Task

Run these commands in R, then use your own words to describe what the resulting numbers represent.You can get some information about the functions by using the help commands in R (such as ?pbinom to get information about the pbinom() command in R):

a) pbinom(q=5, size=10, prob=1/6)

b)

n=10

p=.5

x=9

pbinom(x, n, p)

c) punif(5, min=1, max=10) - punif(4, min=1, max=10)
