Question

Bob works at a construction company. He has an equally likely chance to be assigned

Answer 1

Answer:

$7$ times.

Step-by-step explanation:

We know that there are three buildings that he can be assigned to.

Since there are three buildings, the probability of each crew would be $\frac{1}{3}$.

If you set up the proportion, it would look like this.

$\frac{1}{3}$ = $\frac{x}{21}$

The next step would be to solve for x.

$3x =21$

$x=7$
