So I figured everyone has math, or has had math.

We can help each other!

And yay.

Just figured out the second one!

Anyone wanna help with:

1. What is the probablility that a 9-digit phone number contains at least one 5?(Repetition of numbers and lead zeros are allowed).

3. A box contains 17 yellow, 32 green, and 38 red jelly beans. If 10 jelly beans are selected at random, what is the probability that:
a) 4 are yellow?
B ) 4 are yellow and 5 are green?
c) At least one is yellow?
