Gre4nikov [31]

For this case, the first thing we must do is define variables.
We have then:
x: number of cubic yards of mulch that first truck can transport
y: number of cubic yards of mulch that second truck can transport
Now we write the expression.
The first truck makes 12 trips to a job site:
$12x
$
The second makes 14 trips:
$14y
$
The difference between the first truck and the second truck is:
$12x - 14y$
Answer:
An expression that represents the difference in the total number of cubic yards that the first truck delivers compared to the second is:
$12x - 14y$

krok68 [10]

A fleet of nine taxis is to be dispatched to three airports in such a way that three go to airport A, five go to airport B, and one goes to airport C. In how many distinct ways can this be accomplished?

2.44) Refer to Exercise 2.43. Assume that taxis are allocated to airports at random.

a) If exactly one of the taxis is in need of repair, what is the probability that it is dispatched to airport C?

b) If exactly three of the taxis are in need of repair, what is the probability that every airport receives one of the taxis requiring repairs?

So, my answer to 2.44a is 1/9. Hopefully this is correct at least :)

For 2.44b, my guess was

(3C1)(1/3)(2/3)2 * (5C1)(1/3)(2/3)4 * 1/3

The solutions manual on chegg (which seems to be riddled with errors) says something completely different. Is my calculation correct?
