Probability is the measure of how likely an event is. ... The probability of event A is the number of ways event A can occur divided by the total number of possible.

The probability of an event is the ratio of the number of equally likely oucomes of a trial which are favourable to that event, and the total number of outcomes.

Theoretical probability is the probability of an event when all outcomes are equally likely. With theoretical probability, you determine the probability by dividing the number of ways the event can occur by the total number of equally likely outcomes.

Each outcome has a probability of 0.05

Expected successes= Theoretical Probability · Trials P(event) = Number of possible out comes divided by total number of possible

properties of probability

experimental probability

The probability of the event that comprises the favourable outcome.

Another name for experimental probability is empirical probability. This is the ratio of the number of outcomes in which a specified event occurs to the total number of trials.

the probabilty of both events is true. but which is most reliable is probabilty of B as it is more near to 1( total probabilty of any event)

Probability is the chance (in percentage or decimal) of a particular event to happen. lets say that you tossed a coin. the possible events to happen are ending up with heads or tails. the probability of having a head is 50% or .5 while the probability of having a tails is 50% or .5. to solve for the probability, divide the particular event with the total number of possible events. ex. what is the probability of getting a 3 when you rolled a dice? particular event= having a 3= 1 event total number of events= having either a 1, 2, 3, 4, 5, or 6= 6 events particular event/ total number of events= 1/6 hoped i helped!

That's the same as the total probability (1) minus the probability of seven heads. So: 1 - (1/2)7 = 127/128
