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 in simplest form
Find the theoretical probability of selecting a brown rubber band
The theoretical probability of selecting a brown rubber band is:
P(brown) = number of brown rubber bands / total number of rubber bands
P(brown) = 90 / (90 + 95) = 90/185 = 18/37
