Answer:
35 combinations
Step-by-step explanation:
You have to use the formula for finding combinations in probability. It looks like this:
₇C₃ = [tex]\frac{7!}{3!(7-3)!}[/tex]
so that gives you
₇C₃ = [tex]\frac{7*6*5*4!}{3*2*1*4!}[/tex]
The 4 factorials cancel each other out, and when you do the math, you get 210/6. That divides evenly into 35. So there are 35 combinations.
