We are tasked to solve for the number of ways the 8 students be competing for the 1st, 2nd, 3rd, 4th voilin chair in the schools orchestra. The number of ways if can only be filled is though the formula used in number counting, that is
8x7x6x5
Therefore, there are 1680 ways
Solution: The standard deviation is used in conjunction with the mean to numerically describe distributions that are bell shaped. The mean measures the center of the distribution, while the standard deviation measures the spread of the distribution.
In normal distribution (bell shaped distribution) , the mean and standard deviation are used to describe its distribution. The mean measures the center of the distribution, while the standard deviation takes care of the spread of the distribution.
The mean of the normal distribution is
and the standard deviation is

Answer:
42 games
Step-by-step explanation:
From the ratio, we can deduce that;
For every 3 games A won, B won 1
Thus, if B won 10, then A has won 3(10) = 30
From the second part;
For every 1 game won by C, B won 5
since B won 10, then C won 10/5 = 2
So the total number of games won is;
A + B + C
= 2 + 30 + 10 = 42 games
