1.	What is the probability that a number selected at random from the number 1, 2, 2, 3, 3, 3, 4, 4, 4, 4 will be their average?
Answer» Total number of possible outcomes = 10 Average of the numbers = \(\frac{sum\,of\,the\,given\,n\,numbers}n\) = \(\frac{30}{10}\) = 3 ∴ Number of favorable outcomes, n(E) = 3 ∴ P(E) = \(\frac{n(E)}{n(S)}\) = \(\frac{3}{10}\)

Answer»

Total number of possible outcomes = 10

Average of the numbers = \(\frac{sum\,of\,the\,given\,n\,numbers}n\) = \(\frac{30}{10}\) = 3

∴ Number of favorable outcomes,

n(E) = 3

∴ P(E) = \(\frac{n(E)}{n(S)}\) = \(\frac{3}{10}\)
