Activity Notes We have 4 balls - 2 Reds and 2 Greens. We drop them randomly into 2 boxes.
These (a) Both boxes will have will have 1R & 1G.
(b) One box 2G, other box 2R.
Guided Activity Do the experiment 200-1000 times. - What is the percent of mixed?
- What is the percent of separate?
Now for some dreaded theory ...
- How many different ways can the balls drop into the boxes?
- How many times does mixed occur?
- Does your theory match your experiment?
"Mutually exclusive" meaning both events cannot happen at same time and "complete" meaning no other event can occur. |
