Probability problems(review!)
1.A bag contains 3 red marbles, 3 blues, and 3 yellows. 2 marbles are going to be drawn WITHOUT replacement. What is the chance the both marbles drawn are the same color?
so 3/12(1st draw) and 2/11(second draw) 6/132 = 1/22 yes?
2. What is the smallest integer with EXACTLY 10 divisors.
48? Found this through prime factorization.
The integral of hope is reality.
May bobbym have a wonderful time in the pearly gates of heaven.
He will be sorely missed.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
