Question 1088103: Use the binomial expansion of (p + q)^n to calculate n = 5 and p = 0.3.
a. 0.15 + .006807 + 0.03045 + 0.26537 + 0.197373 + 0.35
b. 0.00243 + 0.02835 + 0.1323 + 0.3087 + 0.36015 + 0.16807
c. 0.00243 + .0.02835 + 0.2646 + 0.3697 + 0.20105 + 0.13397

You can put this solution on YOUR website! .
Absolute and total nonsense.
Please do not post it to the forum again.
Thanks.

I read the post by @MathTherapy, and I want to say THIS:
If after reading the formulation of a Mathematical problem the reader (the qualified reader) still have questions what
the formulation means - then the right place for such problem is in the TRASH section.
And nowhere else.

I take it that you must be doing BINOMIAL EXPANSION. You should also be familiar with p and q, or probability of success (p), and probability of failure (q).
Therefore, with p being .3, q MUST = 1 - .3, or .7
 now becomes: 
Now, as we have a binomial being raised to the 5th power, we're going to have 6 (six) expressions after the binomial has been expanded.
All choices have 6 expressions so none of the choices can be eliminated.
You now need to use what you know about the BINOMIAL EXPANSION formula, and PASCAL'S TRIANGLE, to help you get your answer.
I'll give you a HINT: It's NOT choice a.
