DescriptionProbability Term
When all the outcomes of a random variable cannot be listed, it is _____
Observation of random phenomenon
Combination of possible outcomes
All Possible outcomes in a situation
If two independent events A and B where A=.5 and B=.3, what is the probability of A and B occurring?

The chance that an event will occur
The outcome of one trial doesn't affect the outcome of the others
Events that have no outcomes in common
Synonym for mutually exclusive
For two disjoint events A and B the probability that one or the other occurs is the sum of the probabilities of the two events
