What 3 ways probability can be shown?

If probability of reading newspaper a is .2 probability of reading newspaper b is .16 probability of reading newspaper c is .14.what is the probability that a person selected at random will read none?
The Probability of NOT reading newspaper a is .8 The Probability of NOT reading Newspaper b is .84 The probability of NOT reading Newspaper c is .86 Therefore, .8*.84*.86=0.57792=57.792%
If probability of occurrence of event A is p and that of occurrence of event B is q then what is probability that both the events do not occur?
The answer depends on whether A and B can occur together, that is, if they are mutually exclusive.
What does and mean in probability?
It means multiply, Probaility of A and B means probability of A multiplied by probability of B.
How does one find the probability of A given B compliment?
P(A given B')=[P(A)-P(AnB)]/[1-P(B)].In words: Probability of A given B compliment is equal to the Probability of A minus the Probability of A intersect B, divided by 1 minus the probability of B.
What is the or rule in probability?
Given two events, A and B, the probability of A or B is the probability of occurrence of only A, or only B or both. In mathematical terms: Prob(A or B) = Prob(A) + Prob(B) - Prob(A and B).
What is the probability of picking a number from a population of b numbers?
The probability is 1/b.
What is the probability of a and b if a equals 3 and b equals 4?
a and b both have the probability of 3/4
What is the 'and' rule in probability?
If the probability of A is p1 and probability of B is p2 where A and B are independent events or outcomes, then the probability of both A and B occurring is p1 x p2. See related link for examples.
How do you find the probability of A and B when you don't know the probability of A given B?
If A and B are independent, then you can multiply the two probabilities
The probability of event A occurring given event B has occurred is an example of?
The probability of event A occurring given event B has occurred is an example of conditional probability.

What is the probability of drawing either a 3 or a heart from a regular bridge deck of cards?
The probability of A is denoted P(A) and the probability of B is denoted P(B). P(A or B) = P(A) + P(B) - P(A and B). Say P(A) = Probability of drawing a heart, which is 13/52. Say P(B) = Probability of drawing a three, which is 4/52. We now have to determine P(A and B) which is the probability of a heart and a three, which is 1/52. We now can determine the probability of drawing a heart or a three which is 13/52 + 4/52 - 1/52 = 16/52 = 4/13.
What is the relationship between conditional probability and the concept of statistical independence?
If events A and B are statistically indepnedent, then the conditional probability of A, given that B has occurred is the same as the unconditional probability of A. In symbolic terms, Prob(A|B) = Prob(A).
What is multiplication rule in probability?
Given two events, A and B, the conditional probability rule states that P(A and B) = P(A given that B has occurred)*P(B) If A and B are independent, then the occurrence (or not) of B makes no difference to the probability of A happening. So that P(A given that B has occurred) = P(A) and therefore, you get P(A and B) = P(A)*P(B)
