Question

.
The probability a red marble selected at random from a jar containing p red, q blue
and r green marbles is ?​

Answer 1

$\boxed{\huge\mathfrak{answer}}$

$let \: p(red) = p$

$p(blue) = q$

$p(green) = r$

$p(total) = p(red + green + blue)$

$p(total) = p + q + r$

$now \: p(red) = \frac{p}{p + q + r}$

Answer 2

p/p+q+r
