Probability tools from TI-83 Plus

[QueHuong]

I remember there are a bunch of built-in probability programs for my calc when I took stats in high school, but I forgot what tool to use and what are its parameters.

In biology, we're doing the hardy-weinbergy equilibrium. I don't want to go into detail, but this is what we basically have to do:

Basically, let's say I have two marbles, one green and one yellow. THere are a total of 40 greens and 60 yellows. I have to reach in the bag and randomly select one marble (with replacement); so how do I use the TI-83 to simulate that?

MATH > PRB > randInt(1,10) for a single rep with 1-4=green marble and 5-10=yellow marble. Or you can do randInt(1,10,[number of reps])-->L1:SortA(L1)

I didn't need a calculator to do hardy weinberg.

I didn't need a calculator to do hardy weinberg.

Good for you?

I'm using a calculator to generate random numbers to represent 2 genes so I can use them in the H-W equation.

Thanks, Deslocke, just what I was looking for.

NP. I think you could also do randBin(1,.4,[number of reps])-->L1:sum(L1) and it will give you the number of greens.
