How do you find p in statistics
WebNow, by looking at the formula, Probability of selecting an ace from a deck is, P (Ace) = (Number of favourable outcomes) / (Total number of favourable outcomes) P (Ace) = 4/52. = 1/13. So we can say that the probability of getting an ace is 1/13. Example 2: Calculate the probability of getting an odd number if a dice is rolled. WebTo find the expected value, E (X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as E(X) = μ = ∑xP(x). Here x represents values of the random variable X, P ( x) represents the corresponding probability, and symbol ∑ represents the ...

WebDec 20, 2024 · Actually the standard deviation of Y is square root of the quantity p* (1-p). In the lesson, Y is a random variable that is 1 with probability p, and 0 with probability (1-p). The mean of Y, mu_Y, is E (Y) = 0*P (Y=0)+1*P (Y=1) = 0 (1-p)+1*p = p.
