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.

Find the theoretical probability of selecting a pink rubber band.

Find the theoretical probability of selecting a brown rubber band.

Answer 1

There are a total of 95 + 90 = 185 rubber bands in the box.

The theoretical probability of selecting a pink rubber band is:

95/185

This can be simplified by dividing both the numerator and denominator by 5:

19/37

Therefore, the probability of selecting a pink rubber band is 19/37.

The theoretical probability of selecting a brown rubber band is:

90/185

This can also be simplified by dividing both numerator and denominator by 5:

18/37

Therefore, the probability of selecting a brown rubber band is 18/37.
