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.

Answer:
-cos^4(x)
Step-by-step explanation:
Step 1: Use the Pythagorean identity : 1=cos^2(x) + sin^2(x)
1-sin^2(x) = cos^2(x)
-1+sin^2(x) = -cos^2(x)
cos^2(x) (-cos^2(x))
Step 2: Factor out common terms cos^2(x)
cos^2(x) (sin^2(x)-1)
Ans: -cos^4(x)
