Answer: There is a probability of 0.05 that there is neither truck is available.
Step-by-step explanation:
Since we have given that
Probability that the first truck is available = 0.75
Probability that the second truck is available = 0.50
Probability that both trucks are available = 0.30
So, probability that either first truck or second truck is available is given by
We need to find the probability that neither truck is available.
so, P(A∪B)'=1-P(A∪B)
Hence, there is a probability of 0.05 that there is neither truck is available.
