Abox contains 95 pink runner 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 is simplest form.

a. find the theoretical probability of selecting a pink rubber band.

b. find the theoretical probability of selecting a brown rubber band.

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:

which is the required probability in simplest form.

(B) The theoretical probability of selecting a brown rubber band is given as:

.

which is the required probability in simplest form.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
