A group of 30 students is part of the audience for a game show.mtge total number of people in the audience is 120. What is the theoretical probability of 3 students being selected as contestants out of a possible 10 contestant spots?

P(3 students selected) = Round to three decimal places

Solution

Prob for the given group = 30/120 = 0.25

p =0.25

n = 10

P(x =3) = 10C3(0,25)³(0.75)⁷

= 0.2503

=0.250
