Chapter 13: Q. 36 (page 865)

For Problems 35 and 36, an urn contains 5 white marbles, 10 green marbles, 8 yellow marbles, and 7 black marbles.

If one marble is selected, determine the probability that it is black.

Short Answer

Expert verified

The probability is730.

Step by step solution

01

Step 1. Given information. 

An urn contains 5 white marbles, 10 green marbles, 8 yellow marbles, and 7 black marbles.

02

Step 2. Find probability.

We are given a total of 30 marbles for our sample space nS, That is

5white+10green+8yellow+7black=30

and asked to look for the probability of selecting a black marble. Thus, we can use the formula

Pblack=nblacknS

Since there are 7 black marbles, then n(black)=7

Substituting the value of n(black)andn(S) in the formula:

Pblack=nblacknS=730

03

Step 3. Conclusion. 

The probability is730.
