" 25% of 11 year-old children have no decaved, missing, or filled teeth, (DMF) find the
probability that in a sample of 20 children there will be: List each of the probabilities in your
total.
a.
Exactly 3 with no DMF teeth-- P(x-3) if n=20 and p=.25
b.
3 or more with no DMF teeth-P(x23) if n=20 and p=.25
C.
Fewer than 3 with no DMF teeth-P(x<3) if n=20 and p=.25
d. Exactly 5 with no DMF teeth-P(x%35) if n=20 and p3.25
