Answer:
3,6,9,12,15,18,21,24,27,30...
7,14,21,28,...
Step-by-step explanation:
Yes, use the methods you have learned like the proportional probability method and plug in the values you are trying to solve to help in the real world! Hope this helps!
In general, nCr = n! / r! (n-r)!
Here, 7C3 = 7! / 3!(7-3)!
=7 x 6 x 5 x 4 x 3 x 2 x 1 /3 x 2 x 1 ( 4 x 3 x 2 x 1)
=7x6x5x4 / 4x3x2
=7x5x6x4 / 24
=35x24 / 24
=35
