A group of 125 truck owners were asked what brand of truck they owned and whether or not the truck has four-wheel drive. The results are summarized in the two-way table below. Suppose we randomly select one of these truck owners.

What is the probability that the person owns a Dodge or has four-wheel drive?
$\left(a\right)\frac{20}{80}$
$\left(b\right)\frac{20}{125}$
$\left(c\right)\frac{80}{125}$
$\left(d\right)\frac{90}{125}$
$\left(e\right)\frac{110}{125}$

Given:

Let us first determine the row/column totals, which is the sum of all counts in the row/column.

The table contains 125 people in total, which is given in the bottom right corner of the table.
The people who own a dodge or have four-wheel drive are given in the row "Dodge” and given in the column ”Four-wheel drive” of the above table, which corresponds with 28+ 32+ 20+ 10= 90 people.
Thus 90 of the 125 people own a dodge or have four-wheel drive.
The probability is the number of favorable outcomes divided by the number of possible outcomes:

Answer: (d) $\frac{90}{125}$
