Using the binomial distribution, it is found that there is a 0.056 = 5.6% probability that more than 7 will make a purchase.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- There are 12 customers, hence n = 12.
- The probability of any of them making a purchase is of p = 0.4.
The probability that more than 7 will make a purchase is given by:
P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12).
Hence:
Then:
P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) = 0.042 + 0.012 + 0.02 + 0 + 0 = 0.056.
0.056 = 5.6% probability that more than 7 will make a purchase.

60 because y is substituting for 1 and if a number is 2y that means it is 2 because you multiple 2 and 1.
Given that,
Cost of 6 pounds apples = $4.00
To find,
Unit rate.
Solution,
We have,
6 pounds apples = $4.00
We can find the cost of 1 pound of apples as follows :
1 pound apples =$ (4/6)
= $0.67
So, the cost of 1 pound apples is $0.67.
Take 16x divide it by 2 and square it. 16/2= 8. 8^2= 64. So, the first step will be to add 64 to both sides.
Answer: Our required probability is 0.1695.
Step-by-step explanation:
Since we have given that
Number of male applicants = 4200
Number of female applicants = 3800
So, total number of applicants = 4200+3800 = 8000
Probability of male entered and subsequently enrolled is given by
Probability of female entered and subsequently enrolled is given by
Number of male entered and subsequently enrolled is given by
Number of female entered and subsequently enrolled is given by
So, Probability that a student who applied for admission will be accepted by the university and subsequently will enroll is given by
Hence, our required probability is 0.1695.
