a. The theoretical probability of selecting a pink rubber band would be:
P(pink) = number of pink rubber bands / total number of rubber bands
P(pink) = 95 / (95 + 90)
P(pink) = 19/38
b. The theoretical probability of selecting a brown rubber band would be:
P(brown) = number of brown rubber bands / total number of rubber bands
P(brown) = 90 / (95 + 90)
P(brown) = 18/38
c. The experimental probability of selecting a pink rubber band would be:
P(pink) = number of times pink was selected / total number of selections
P(pink) = 36 / (36 + 33)
P(pink) = 12/21
P(pink) = 4/7
The experimental probability of selecting a brown rubber band would be:
P(brown) = number of times brown was selected / total number of selections
P(brown) = 33 / (36 + 33)
P(brown) = 11/21
A box contains 95 pink rubber bands and 90 brown rubber bands. You select a rubber band at random from the box. Find each probability. Write the probability as a fraction in simplest form.
