Vaselesa [24]

Answer: Second Option

P =0.00476

Step-by-step explanation:

The probability sought is calculated by calculating the quotient between the number of possible ways to select 4 seniors from a group of 4 seniors among the number of ways to select 4 seniors from a group of 10 people.

So:

P =\frac{4C4}{10C4}

Where

nCr = \frac{n!}{r!(n-r)!}

is the number of ways in which a number r of people can be selected from a group of n people

Then

P =\frac{\frac{4!}{4!(4-4)!}}{\frac{10!}{4!(10-4)!}}\\\\\\P =\frac{1}{\frac{10!}{4!(10-4)!}}\\\\P =\frac{1}{210}\\\\P=0.00476
