Jan 31 comment Find the solutions to ${ 450 }^{ { (\sin x) }^{ 3 } }+{ 273 }^{ { (\cos x) }^{ 5 } }=2$ Every number is this equation is weird. Jan 31 comment Probability of getting 5 multiple-choice questions answered correctly @BenSewards You still didn't say the total number of questions. Jan 31 comment Probability of getting 5 multiple-choice questions answered correctly @anorton I think 5 is the number of questions answered correctly. Jan 31 comment Probability of getting 5 multiple-choice questions answered correctly It is impossible to get $45/118$ as OP mentioned. Jan 31 revised closest point to on $y=1/x$ to a given point added 6 characters in body; edited title Jan 30 comment Conditional Distributions and Probabilities $Y$ is a continuous random variable. Isn't it true that $Pr(Y=y|\eta)=0$? Jan 30 comment Let $X$ and $Y$ be two Poisson random variables with same lambda parameter. What is the distribution of $\frac{X}{X+Y}$? I am not sure what this distribution is, but it's definitely not uniform on $[0, 1]$. Jan 30 revised Let $X$ and $Y$ be two Poisson random variables with same lambda parameter. What is the distribution of $\frac{X}{X+Y}$? added 8 characters in body Jan 30 revised Integrating the pdf of a normal distribution deleted 2 characters in body Jan 29 revised Probability involving Method of Moments added 5 characters in body Jan 29 revised Approaches to integrate $\int_0^1 \frac{x}{\sqrt{a+bx+cx^2}} dx$ latex symbols updated Jan 29 comment Limit of a Function: $\lim_{x \to 0}\ (e^x + x)^ {\large \frac {1} {x}}$ This doesn't convince me. Jan 29 comment maximising the frequency of mode. What do you mean by "distribute"? And what does "(give $2$ to $3$)" mean? Jan 29 revised added 140 characters in body Jan 29 awarded Tag Editor
