Probability of Two Events Occurring Together: Independent Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.

Once again, the Counting Principle requires that you take the number of choices or outcomes for two independent events and multiply them together. The product of these outcomes will give you the total number of outcomes for each event. You can use the Counting Principle to find probabilities of events.

- P(A and B) = 0 if two events are mutually exclusive, then the probability of either occurring is the same of the probabilities of each occurring. - If two events are mutually exclusive, they cannot be independent and vice versa.

Events A and B are independent if: knowing whether A occured does not change the probability of B. Mathematically, can say in two equivalent ways: P(B|A) = P(B) P(A and B) = P(B ∩ A) = P(B) × P(A).

Determining the probability of a compound event involves finding the sum of the probabilities of the individual events and, if necessary, removing any overlapping probabilities. An exclusive compound event is one in which the multiple events do not overlap. In mathematical terms: P(C) = P(A) + P(B).

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true. You can use the equation to check if events are independent; multiply the probabilities of the two events together to see if they equal the probability of them both happening together.

Product rule for independent events If A and B are independent, P(AB)=P(A)P(B) (because P(A|B)=P(A) for independent events). (Example: If A and B are independent and P(A)=.

Divide the number of events by the number of possible outcomes. After determining the probability event and its corresponding outcomes, divide the total number of events by the total number of possible outcomes.

The probability of the events are said to be disjoint, meaning that they cannot interact, are strictly independent. If the probability of event A is mutually exclusive with event B, then the joint probability of event A and event B is zero.

Since the genes are unlinked, these are four independent events, so we can calculate a probability for each and then multiply the probabilities to get the probability of the overall outcome. The probability of getting one or more copies of the dominant A allele is 3 / 4 3/4 3/4 .

SOLUTION: suppose a and b are independent events what if p (a)=0.5 and p(b) =0.45 what is p( a n b) When the independent the product of the two is the joint probability. If it is p( a and b), it is 0.5*0.45=0.225.

According to the definition of independent events, A and B∪C are independent if and only if P(A∩(B∪C))=P(A)P(B∪C). Since A and B and A and C are independent, I know that P(A∩B)=P(A)P(B)andP(A∩C)=P(A)P(C).

To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none). Topford supplies X-Data DVDs in lots of 50, and they have a reported defect rate of 0.5% so the probability of a disk being defective is 0.005.

['Define Success first. Success must be for a single trial. Success = "Rolling a 6 on a single die"', 'Define the probability of success (p): p = 1/6.', 'Find the probability of failure: q = 5/6.', 'Define the number of trials: n = 6.', 'Define the number of successes out of those trials: x = 2.']

Rule 3: If two events A and B are disjoint, then the probability of either event is the sum of the probabilities of the two events: P(A or B) = P(A) + P(B). The chance of any (one or more) of two or more events occurring is called the union of the events.

SOLUTION: if A and B are independent events P(a)=. 4 and P(B)=. 6 find P(A U B) P(A U B) = P(A) + P(B) - P(AB) = 0.4 + 0.6 - 0.24 = 0.76.

Let A and B be independent events, and let A and C be independent events. ... According to the definition of independent events, A and B∪C are independent if and only if P(A∩(B∪C))=P(A)P(B∪C).
