Events A and B are independent if probability of A given B equals probability of A. Dependent events (or non-independent events): Events that are not ... |
The following formula is used to calculate the expected value: Expected V alue = P (A) ⇥ (P rofit/Loss from A) + P (B) ⇥ (P rofit/Loss ... |
Let E and F be events associated with the sample space S of an experiment. Then: (i) P (S | F) = P (F | F) = 1. (ii) P [(A ∪ B) | F] = P (A | F) + P (B | F) ... |
P (A) = n(A) n(S) Equal Likelihood, the formula that we apply to calculate probability, Number of favorable outcome Number of total outcome , is valid only ... |
number of successes (or x) probability of success. = probability of failure. 1. = 1. Binomial probability distribution. ( ). Mean: Standard deviation:. |
Let x1,x2,... be the possible values of X, each with probabilities. P1, P2,... Then we can consider a probability distribution function (p.d.f) for f(x). |
These notions can be extended to define the joint (simultaneous) probability distribution and the marginal distributions of n random variables. |
