Quesiton : P(A) + P(A-) = 1 is one way to express the _
Answer: P(A or B) indicates
P(A) + P(A-) = 1 is one way to express the _ P(A or B) = 1/2. Note that "or" is another way to express "union". The term "and" denotes the "intersection". Find (a) P(A and B) (b) P(A and B' ) (c) P(A|B) (d) Are the events A and B mutually exclusive? Why or why not? (e) Are A and B independent events? Why or why not? I am confused how P(A or B) can equal 1/2. It would be great though if you could … Ex 13.2 9 (Method 1) If A and B are two events such that P (A) = 14 P (B) = 14 and P(A ∩ B) = 18 find P (not A and not B). Given P(A).. P(F) = the probability of event F occurring The probability of rolling a 1 2 or 3 is 3/6 = 1/2; P(E|F) = the probability of event E occurring given that event F has already occurred If event F already occurred we are limited to the numbers 1 2 or 3. Within this range of 3 possible numbers only one number--namely 2--is an even number. Get this answer with Chegg Study View this answer. OR.

Keeping in the spirit of (1) we denote a binomial n p r.v. by X ∼ bin(n p). 3. geometric distribution with success probability p: The number of independent Bernoulli p trials required until the first success yields the geometric r.v. with p.m.f. p(k) = ˆ p(1−p)k−1 if k ≥ 1; 0 otherwise. P-value > α: The differences between the means are not statistically significant If the p-value is greater than the significance level you do not have enough evidence to reject the null hypothesis that the population means are all equal. Verify that your test has enough power to detect a difference that is practically significant.
