Now swap the 5 for 50, the 0.5 for 0.02 and you see that there indeed is a possibility to get 0 heads and thus you need to consider it when calculating P(x=<2). The same holds for the nonconforming units, which shows the beauty of probability and stats: the essentially same ideas are applicable to so many different examples. $\endgroup$

2022年3月21日 · $\begingroup$ There are already two votes to close this question as duplicate. I don't agree. This is a pretty basic topic, one of those that will probably re-appear in the future, so it would be good if it had a direct and high quality answer, so we could refer to it in the future.

2020年11月6日 · Apologies for the simple question. In several sources I found these defitions: 1) P(X) represents the probability of X. 2) P(X = x) refers to the probability that the random variable X is equal to a

2011年5月11日 · Suppose that P(X=0)=1-P(X=1). If E[X]=3Var(X), nd P(X=0). Well the answer is 1/3 which i cannot seem to get. I calculate P(X = 1) = p thus P(X = 0) = 1 - p Var(x) = (1 - p)/p^2 E(x) = 1 / p Solving this u get p = 3(1 - p) and thus p = 3/4...so P(x = …

2018年7月22日 · How to factor the polynomial #P(x)# and then solve the equation #P(x)=0# for the given below? (1) #P(x)=x^3-6x^2-x+6# (2) #P(x)=x^4-x^3-19x^2+49x-30#

If we wanted to make a separate prize for each possible stopping point, we would have to partition the wheel in an infinite number of "sectors" of equal area (but each of those would have an area of 0).

2015年3月20日 · Quoting Wikipedia: In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function that describes the relative likelihood for this random variable to take on a given value.

2017年3月6日 · P(X>5) = 0.8 The standard notation is to use a lower case letter to represent an actual event, and an upper case letter for the Random Variable used to measure the probability of the event occurring.
