Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Probability of owned a sedan = 39%
Probability of owned a van = 33%
Probability of owned a sports car = 7%
n = 3
We need to find the probability that all three randomly selected households own a van.
So, Probability of getting all 3 own a van is given by

Hence, Option 'a' is correct.
Answer:
0.0792 = 7.92% probability that there is an inconclusive (tied) voting outcome
Step-by-step explanation:
For each juror, there are only two possible outcomes. Either they vote correctly, or they do not. The probability of a juror voting correctly is independent of any other juror. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
12 members
This means that 
Suppose that the probability that a juror votes correctly (i.e. in line with the actual innocence/guilt of the person on trial) is 70%
This means that 
What is the probability that there is an inconclusive (tied) voting outcome?
Same number(12/2 = 6) of votes for each option, so P(X = 6).


0.0792 = 7.92% probability that there is an inconclusive (tied) voting outcome
It is 40 40. 40 is the answer
