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 pink rubber band
The theoretical probability of selecting a pink rubber band is:
P(pink) = number of pink rubber bands / total number of rubber bands
P(pink) = 95 / (95 + 90)
P(pink) = 95 / 185
P(pink) = 19 / 37
Therefore, the probability of selecting a pink rubber band is 19/37 or approximately 0.514.
