Wrong (in either scenario).

I won't solve it for you, OP, but here's a hint: is it geometric or binomial distribution?
I used the binomial distribution formula

P(X) = n! pX(1-p)n-x
X! (n-x)!

You have the correct formula; use it.

0.02835 is incorrect.

Nope.

It looks now as though you're guessing. Use the formula. What's p? What's n? What's x?
