Answer:
When simplified they all are 1/5
So yes they are proportional
2.5 is the mean of this distribution.
What is the distribution's mean?
- The expected value, commonly known as the mean of a statistical distribution with a continuous random variable, is calculated by integrating the product of the variable's probability as described by the distribution.
- The lowercase Greek letter mu () stands for the expected value. A probability of 50% equals zero standard deviations, and the mean is in the middle of the normal distribution.
Given: p = 0.05 and n= 50
Mean of the binomial distribution = n×p = 50 × 0.05 = 2.5
Therefore, option a is the correct answer. Other options are incorrect because these are irrelevant.

Step-by-step explanation:
If you want step by step explanation you can get your explanation from
https://www.mathpapa.com And just type that answer in where it says what do you want to calculate? type it in that box and it give you step by step but i gave you the answer up top you just need the explanation the explanation is hard to type in here that's why i have you that website :)
5.7 is 5 7/10 and it cannot be simplified
6/10 - 1/2...common denominator is 10
6/10 - 5/10 = 1/10 <==
