Answer:
1.D) Procedure results in a binomial distribution.
2. B) Procedure results in a binomial distribution.
Step-by-step explanation:
The binomial distributions has following properties.
- There is always one of the two outcomes success or failure possible.
- The probability of p remains constant for all trials.
- The successive trials are all independent.
- The experiment is repeated for a fixed number of times.
If the experiment has the above properties it has binomial probability distribution.
In the given question both experiments have the above mentioned properties.
Both procedure result in binomial distribution.

Answer:
This is what you have to explain:
With 5n, you are multiplying a number and a variable.
With 5 + n, you are adding a number and a variable.
Answer:
Step-by-step explanation:
Probability is the ratio of the required outcome to the total possible outcome
Total outcome = 75
Number of times target was hit (expected outcome) = 41
Pr(she will hit target)= 41/75
Next is to state in percent and u do that by multiplying the resulting fraction by 100
41/75 i n percent.
41/75×100
= 4100/75
= 54.67%
Hence the answer in percentage is 54.67%
