Explain How To Find The Probability Of An Event - How To Find. The way we calculate this probability depends on whether or not events a and b are mutually exclusive or not. The probability of wearing the blue sweater is 50% or the odds are 1 out of 2.

P(a∪b) = p(a) + p(b) Conditional probability for independent events. Now to fair dice are rolled a green one and a red one. To solve more difficult problems and derive an expression for the probability of a general binomial distribution, we need to understand the concept of permutations and combinations. Due to this reason, the conditional probability of two independent events a and b is: Calculate p (a \cap b). Find the probability of the next person you meeting having a phone number that ends with 5? The probability of the first and second event might not be the same. Find the probability that the person that meet next has a birthday in february? P(a∩b) = (1/30) * (1/32) = 1/960 =.00104.
P(a and b)= probability of both a and b events occurring. For example, if the second event is throwing a 4 with one die, the probability is the same as the first event: Event b b is the spinner landing on an even number. Event a a is the spinner landing on blue. Let's pick something a little silly but simple as an example. Probabilities of events add up to 1, so to find the probability of the spinner showing a 4, add up the remaining probabilities and subtract this from 1. The probability of the first and second event might not be the same. Let's look at an example. Due to this reason, the conditional probability of two independent events a and b is: Determine the probability of the second event. P(b) = probability of event b.
