If there are 323 occurrences, the expected value is ?
Probability is the likelihood or chance that a particular event will happen. If the probability of an event occurring is 0 that means the event is impossible, and 1 means the event is certain. To calculate probability, divide the number of favorable outcomes by the total number of possible outcomes.For example, if you want to calculate the probability of drawing a red marble from a bag containing 5 red marbles and 10 blue marbles
Identify the number of favorable outcomes (in this case, 5 red marbles)
Identify the total number of possible outcomes (in this case, 15 total marbles)
Divide the favorable outcomes by the total outcomes to get the probability
