Answer:
5% probability neither truck is available
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that the first truck is available.
B is the probability that the second truck is available.
We have that:
In which a is the probability that the first truck is available and the second one is not is the probability that both trucks are available.
By the same logic, we have that:
The probability that both trucks are available is .30.
This means that
The probability the second truck is available is .50
This means that . So
The probability the first truck is available is .75
This means that . So
The probability that at least one truck is available is:
The probability that neither truck is available is:
5% probability neither truck is available
