Get started for freeFrom a well shuffled deck of ordinary playing cards, four cards are turned over one at a time without replacement. What is the probability that the spades and red cards alternate?
Bowl I contains 6 red chips and 4 blue chips. Five of these 10 chips are selected at random and without replacement and put in bowl II, which was originally empty. One chip is then drawn at random from bowl II. Given that this chip is blue, find the conditional probability that 2 red chips and 3 blue chips are transferred from bowl I to bowl II.
If \(X\) is a random variable such that \(E(X)=3\) and \(E\left(X^{2}\right)=13\), use Chebyshev's inequality to determine a lower bound for the probability \(P(-2<\) \(X<8)\)
Let \(0
Let \(X\) be a random variable with mean \(\mu\) and variance \(\sigma^{2}\) such
that the third moment \(E\left[(X-\mu)^{3}\right]\) about the vertical line
through \(\mu\) exists. The value of the ratio \(E\left[(X-\mu)^{3}\right] /
\sigma^{3}\) is often used as a measure of skeuness. Graph each of the
following probability density functions and show that this measure is
negative, zero, and positive for these respective distributions (which are
said to be skewed to the left, not skewed, and skewed to the right,
respectively).
(a) \(f(x)=(x+1) / 2,-1
