You can put this solution on YOUR website! A pet shop is selling a calico cat, a Siamese, persian, and a Himalayan cat. The Chens are going to select two cats to bring home as pets.
----------------------
a. determine the number of points in the sample space.
4C2=6 pairs of cats
--------------------
b. construct a tree diagram and list the sample space
1st column: calico, siamese, persian, Himalayan
2nd column: siamese,himalayan, and persian next to calico
calico, himalayan, and persian next to siamese
calico, himalayan, and siamese next to persian
calico, persian, calico, next to himalayan
--------------
c. find the probaility that they will select the Persian cat, the Persian cat and the Calico,cats other than the Persian Cat
Prob(persian)= 6/12=1/2
Prob(persian and calico)=2/12=1/6
Prob(not persian)=6/12=1/2
-----------
