Project Notes

We have 4 balls - 2 Reds and 2 Greens. We drop them randomly into 2 boxes. Click on "Cat 1 Try" to see the idea.

The following two events are mutually exclusive and complete.

(a) Both boxes will have 1R/1G. We call this event: MIXED.

(b) One box 2G, other box 2R.
We call this event: SEPARATE.

Play this applet to find out the probability of each of these 2 events.

(Mutually exclusive: no 2 events can occur at the same time; complete: no other event can occur.)
