e
Step-by-step explanation:
From the question we are told that
The number of car in the parking lot is n = 30
The number of cars in great shape is k = 10
The number of cars in good shape is r = 16
The number of cars in poor shape is q = 4
The number of cars that were selected at random is N= 4
Considering question a
Generally the number of way of selecting four cars that are in a poor shape from number of cars that are in poor shape is
=>
Here C stands for combination.
Generally the number of way of selecting four cars that are in a poor shape from total number of cars in the parking lot is
=>
Generally the probability that every car selected is in poor shape is mathematically represented as
Considering question b
Generally the number of way of selecting 2 cars that are in good shape from number of cars that are in good shape is
=>
Here C stands for combination.
Generally the number of way of selecting the remaining 2 cars from the remaining number of cars in the parking lot is
=>
=>
Generally the number of way of selecting 3 cars that are in good shape from number of cars that are in good shape is
=>
Generally the number of way of selecting the remaining 1 cars from the remaining number of cars in the parking lot is
=>
=>
Generally the number of way of selecting 4 cars that are in good shape from number of cars that are in good shape is
=>
Generally the probability that at least two cars selected are in good shape
Considering question c
Generally the number of way of selecting 3 cars that are in great shape from number of cars that are in great shape is
=>
Generally the number of way of selecting the remaining 1 cars from the remaining number of cars in the parking lot is
=>
=>
Generally the probability of selecting exactly three cars selected are in great shape is
Considering question d
Generally the number of way of selecting 2 cars that are in good shape from number of cars that are in good shape is
=>
Generally the number of way of selecting 2 cars that are in great shape from number of cars that are in great shape is
=>
Generally the probability that two cars selected are in great shape and two are in good shape.
Considering question e
Generally the number of way of selecting 1 cars that is in good shape from number of cars that are in good shape is
=>
Generally the number of way of selecting 3 cars that are in a poor shape from number of cars that are in poor shape is
=>
Generally the probability that one car selected is in good shape but the other 3 selected are in poor shape is
