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.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer: b
