solution In Morse code, dots and dashes are sent in the ratio 3:4, but transmission errors cause a dot to be come a dash with probability 1/4 while a dash is incorrectly read as a dot with probability 1/6. Assuming any two signals are independent of each other, find the probability distribution of the message actually sent when a "dash-dot-dot" is received.

proof Let $X\,$ be the number of events per unit time, so that $X ˜Poisson(λ)$ . Prove that $T\,$ , the time between successive events, has an exponential distribution with rate parameter $\lambda\,$ .

proof Let $X ˜N(μ,σ 2)$ be a normal random variable. Derive $F_X(x)\,$ , the cdf of $X\,$ , in terms of the error function from calculus, ${\rm Erf}(x)=\int_0^xe^{-y^2}\,dy$ .

solution A continuous random variable $X\,$ has a pdf of the form $f(x)=\begin{cases}ce^{-2x}&x>1\\0&x\leq1,\end{cases}$ where $c$ is a constant. Find the value of $c$ and the cdf of $X\,$ .

PROBABILITY AND STATISTICS BOOKS

solution Let us have an array of $N$ numbered elements, p.e., $\{1,2,\ldots,N\}$ . Let the array be randomly reordenated. Find the probability of finding none of the elements in its original position when $N\to\infty$ .
