Follow-up Question

In Step 2 of the answer, I don't understand how to calculate.

 P(X= 8) = 10C8*(0.70)8*(1-0.70)10-8

what is 10C8? where does the number come from? 

Then is it multiplied times (0.70)8

(1-0.70)10-8 does this equal (0.30)2?

If you multiply the three numbers you get the probability

 

Same goes for step 3
