[@hamzahwaheed9528]

Has this ever come up in the new specification?

[@andrewl372]

I can't understand why the probabilities won't be squared when we are finding E(X^2)? Thank you in advance

[@reanimatorism]

because the square is on the x that means we would square the x values

[@andrewl372]

@@reanimatorism thank you

[@drtheman9074]

i also am a big fan of big buff men

[@KanzaIltaf]

you are not taking square root at the end of the variance

[@sultown4343]

that's only needed to get standard deviation.

[@yungzed]
