Answer:
 44%
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the values are is important(0123 is a different password of 3210), which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

Desired outcomes:
One number, from a set of 10
Three characters, from a set of 26.
They can be in 4 possible orders(CNNN, NCNN, NNCN, NNNC). So

Total outcomes:
Four characters, from a set of 26 + 10 = 36. So

What is the approximate probability that exactly one of the four characters will be a number?

So 44%.

Answer:
Pickup trucks 1/4 = 25%
25% of 64 cars = 16 Pickup trucks
Leaving us with 48 cars left.
"twice as many cars as there are SUVs."
32 = cars
16 = SUVs
