1.A cooler at a picnic contains 100 cans of soda covered by ice. There are 45 cans of cola, 26
cans of orange soda, 19 cans of ginger ale, and 10 cans of root beer. The cans are all the same
size and shape. If one can is selected at random from thecooler, determine the probability that the
soda selected is
cola, ginger ale or orange soda.
P (cola) =45/100=9/20
P (ginger ale) =19/100
P (orange soda) =26/100=13/50
P (cola, ginger ale or orange soda)=P(cola)+P(ginger ale)+P(orange
(Simplify your answer. Type a fraction.)
2. In a family with 3 children, excluding multiplebirths, what is the probability of having 3 girls?
Assume that a girl is as likely as a boy at each birth.
Since a girl is likely as a boy at each birth, the probability of a girl is ½ and that of a boy is ½.
