Probability Question

Question

probability problems: 3 students are students of 14. Four students in the class are to be selected at random to present a report. What is the probability that the 3 students are among the four students to be selected?

Answer 1

Duplicate submission (by another student)...look for it!

Answer 2

Let's say (about the 3 students that they are Andy, Bob & Charlie).

 

P(A, B, C & any other student) = ₃C₃•₁₁C₁ ÷ ₁₄C₄

 

That's the answer--I'll let you calculate it.
