Web19 sep. 2024 · Sorted by: 7. The answer to your confusion is that in order for three events A, B and C to be mutually independent it is necessary but not sufficient that P ( A ∩ B ∩ C) = P ( A) × P ( B) × P ( C) (condition 1). The other condition that must be met is that each pair of events must also be independent [so A and B must be independent, B and ... WebGiven P (X) = 0.5, P (Y) = 0.4, and P (Y X) = 0.3, what are P (X and Y) and P (X or Y)? Answer choices: A. P (X and Y) = 0.9, P (X or Y) = 0.75 B. P (X and Y) = 0.9, P (X or Y) …

Web25 apr. 2013 · The Binomial Distribution. Suppose we conduct an experiment where the outcome is either "success" or "failure" and where the probability of success is p.For example, if we toss a coin, success could be "heads" with p=0.5; or if we throw a six-sided die, success could be "land as a one" with p=1/6; or success for a machine in an … WebJoint Probability Distributions Example 1: The joint distribution of p(x;y) of X (number of cars) and Y (the number of buses) per signal cycle at a traffic signal is given by y p(x,y) 0 1 2 x 0 0.025 0.015 0.010 WebIf a random variable X has density function f (x) = { 1 2, − 1 < x < 1 0. otherwise then P ( X >1) is: Q2.
