In order to find the mean, you first count how many numbers are there. Then, you add all numbers together and divide them by the total of numbers. In this case, you would add (1+2+1+0+3+4+0+1+1+1+2+2+3+2+3+2+1+4+0+0+2+2+1+1+1), which equals to 40. The total of numbers is 25. You divide 40 by 25, and it would get you 1.6. Therefore, your mean is 1.6.
To calculate the median, you list the numbers from least to greatest, and find the middle number. The list for this survey would be 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 4, 4. The middle number of this list is 1, therefore, your median is 1.
The mode is simply the number that appears the most in this list. There are 4 zeroes, 9 ones, 7 twos, 3 threes, and 2 fours. The most in this list would be 1, because there are 9 of them. Your mode is 1.
Mean - 1.6
Median - 1
Mode - 1

Applying Binomial Theorem
Here,
a = x, b = 2 and n = 4
So,
Expanding the summation
Answer:
Step-by-step explanation:
If Marios share is 3 parts and is £96, then
Find one part = 96/3 = 32
So,
Rachel receives = 32 x 4 = £128
Sanjay receives = 32 x 9 = £288
Hope this helps
