Answer 1

$\huge \boxed{ \fcolorbox{cyan}{red}{Answer \: }}$

$\sf{p(both \: have \: different \: birthdays}$

$\sf{p(both \: will \: not \: have \: same \: birthdays)}$

$\sf{ = 1 - p(both \: will \: have \: same \: birthday)}$

$\rm{1 - \frac{1}{365}}$

$\rm{ \frac{365 - 1}{365}}$

$\sf{ \frac{364}{365}}$
