Step-by-step explanation:
If 3/4 of the lot was full and the lot holds 1000 vehicles, then there are 3/4(1000) in the lot. 3/4(1000) = 750. That means there are 750 vehicles in the lot. If 200 cars are in the lot, then 750 - 200 = 550 trucks.
Answer: The required probability is 0.334.
Step-by-step explanation:
Since we have given that
N = 15 reservations
probability of reservations will not be used = 0.2
probability of reservations will be used = 1-0.2=0.8
Let X be the Binomial variable,that the number of reservations canceled.
We need to find the probability that more than 8 but less than 12 reservations.
So, it becomes,

Hence, the required probability is 0.334.
