Level 6: Coordinate sample space, probability, and relative frequency for aggregate events.
6A
For compound (aggregate) events, relate sample space to probability.
"When I toss a coin twice, there are 4 possible sets of outcomes: (H,H), (T,T), (H,T), (T,H), each has a probability of 1/4 ."
"The probability of getting a sum of 7 when 2 dice are rolled is 1/6 , because there are 36 outcomes in the sample space, and 6 of them have a sum of 7 (like 3 and 4, 5 and 2, etc)."
