The mean of this data is 212.5454 repeating.
To find the mean you need to find the average and to do that you need to add all values and divide by the number of values. When you add all of those numbers, you get 4676. There are 22 values so you would divide 4676 by 22. This answer is 212.5454 repeating.
The wings of the butterfly would be 67 millimeters
Answer:
The Theoretical probability is 1/6.
The experimental probability is 1/5
Step-by-step explanation:
Given
Rolls: 100
Outcome of 3 : 20
Required
Which of the options is true (See attachment for options)
From the attachment, we understand that the question requires that we calculate the experimental and theoretical probability.
The experimental probability (E) is calculated as thus:



The theoretical probability (T) is calculated as thus:
A cube has 6 faces, one of which is the face 3.
So, T is:


Hence, C is true
8/40 is equal to 20%-students
5/10 is equal to 50%- teachers
