Answer:
Step-by-step explanation:
It is given that A box contains 95 pink rubber bands and 90 brown rubber bands.
Then, the number of pink rubber bands=95,
Number of brown rubber bands=90 and
the total number of rubber bands=95+90=185.
Now, (A) The theoretical probability of selecting a pink rubber band is given as:
\(P(Pink band)=\frac{Number of pink bands}{total number of bands}\)
\(P(pink bands)=\frac{95}{185}=\frac{19}{37}\)
which is the required probability in simplest form.
(B) The theoretical probability of selecting a brown rubber band is given as:
\(P(Brown band)=\frac{Number of brown bands}{total number of bands}\)
\(P(Brown bands)=\frac{90}{185}=\frac{18}{37}\).
which is the required probability in simplest form.
