How to solve or probability
WebOct 30, 2012 · You have counted the probability that both happen twice. You have two events A is the event that a head comes up, and B is the event that a 5 or 6 comes up. The events are independent presumably, so the inclusion-exclusion formula gives: p ( A ∪ B) = p A + p B − p ( A ∩ B). WebProbability is: (Number of ways it can happen) / (Total number of outcomes) Dependent Events (such as removing marbles from a bag) are affected by previous events. Independent events (such as a coin toss) are not affected by previous events. We can calculate the probability of two or more Independent events by multiplying.

WebWe can use the binomial distribution table to find these probabilities, or we can use the binomial formula and add the probabilities manually: P (x < 5) = 0.0282 + 0.1211 + 0.2335 + 0.2668 + 0.2001 P (x < 5) = 0.8497 (rounded to 4 decimal places) Therefore, the probability that x is less than 5 is approximately 0.8497.
