Hi Everyone,
Review the criteria for a binomial in the announcements before selecting your problem.
Example
a) On this example we will examine the probability a couple who has 8 children and has exactly 5 boys.
b) Next we will look at the probability that they have more than 5 boys.
c) Finally we will look at the probability that they have at most 5 boys.
Assume a .5 chance of having a boy.
Solution can be solved using excel.
a) On this example we will examine the probability a couple who has 8 children has exactly 5 boys.
Type this in an excel cell
=binom.dist(5,8,.5,False)
and then hit enter
.21875 would be the answer
b) Next we will look at the probability that they have more than 5 boys.
Type this in an excel cell
=1-binom.dist(5,8,.5,True)
and then hit enter
.144531 would be the answer
c) Finally we will look at the probability that they have at most 5 boys.
Assume a .5 chance of having a boy.
Type this in an excel cell
=binom.dist(5,8,.5,True)
and hit enter
.855469 would be the answer
