Answer 2

${\large{\underline{\underline{\color{navy}{\bigstar{\textbf{\textsf{\color{royalblue}{Given~:}}}}}}}}}$

$\large\sf{Total~outcomes~=~1000}$

$\large\sf{Frequency~of~head~=~455}$

$\cal\colorbox{pink}{To~find~the~frequency~of~tail,~subtract~455~from~1000~which~is~545}$

$\large\sf{Frequency~of~tail~=~545}$

${\large{\underline{\underline{\color{navy}{\bigstar{\textbf{\textsf{\color{royalblue}{Now~lets~find~the~probability~of~head~and~tails~:}}}}}}}}}$

Probability of head = $\sf\dfrac{No.~of~times~head~appeared}{total~no.~of~times~coin~tossed}$

$\implies\sf\dfrac{455}{100}=\color{red}{0.455}$

Probability of tails = $\sf\dfrac{No.~of~times~tail~appeared}{total~no.~of~times~coin~tossed}$

$\implies\sf\dfrac{545}{100}=\color{red}{0.545}$
