9 A (1) is a measure of how likely an event is to occur. The more likely an event is to occur, the (2)_ its probability. The probability of an (3) is a number from 0 to 1 which tells how likely an event is to happen. It is a number either a (4) , (5) (6) If an event is sure to happen, then the probability of the event is (7) and if the event will never happen, it's probability is (8) The total probabilities of all the outcomes in the sample space is also (9) - To find the probability of a simple event, divide the number of favorable outcomes to the (10)​
