More Probability

Big Idea: " the chronology of probability exprienment effects subsequent trials/experiments.
ex) flip a coin; roll a die ARE totally independent
no effect on each other at all each time the "reset" button is hit.

Replacement vs. No Replacement

Independent "reset"
ex) independent/dependent
Dependent-a)eat a sandwitch;long for a sandwitch later
independent-b)write a computer program to generate random #'s.

Ex) Box x/ 2 Red Marbles
Draw 2 marbles. 3 white marbles
P(Both marbles are white)
