Probability, Event

Recall:
Experiment is defined as an activity which can be done repeatedly under similar conditions, and which can result in an outcome.
Ex. 1. Tossing a coin
2. Rolling a die

Sample Space- is the set of all possible outcome.
Ex. 1. Sample space for tossing a die is {Head, Tail}
2. rolling a die sample space is {1,2,3,4,5,6}

Event- is any subset of a sample space.
Ex. 1. In tossing a coin Head is one event and Tail is another possible event. Formula: [1 *2(H,T)]=2 events
2. In Rolling a die, 1 is one event the same thing as 2, 3, 4, or as another event.
Formula (1*6=6 events)
Ex 3. Enumerate the possible events of tossing three coins. Formula 2* 2*2= 8 events
HHH, HHT, HTH, THH, TTH, THT, HTT, TTT

Ex. 4 Enumerate the possible events of rolling 2 dice. Formula 6*6= 36
