The main objective is to find what percent of all commuters travel alone to work?

From 125(a), one have the table as shown below:

Step-by-step explanation

The formula to find the probability of an event A is defined as .

Here, assume that the walkers walk alone and the other groups is none.

Then, the percent of all commuters travel alone to work is     or 77.08%.
