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?
Yeah right now I'm kinda struggling with the rest of them. Boo.
What was the answer to the balls in a box problem?
