Answer 2

${\sf{\underline{\blue{Solution :}}}}$

⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

$\tt{When\: two \:coins\: are \:tossed \:the }$$\tt{results \:are \:(HH,HT,TH,TT)}$

$\tt{Total \:no. \:of\: outcomes\: =\:4}$

⠀ ⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

$\tt{a) \:Exactly\: one\: head \:= }$$\tt{only\: two \:cases \:are\: (HT,TH)}$

⠀ ⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

↠$\tt\frac{2}{4}=$$\tt\frac{1}{2}$

⠀ ⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

$\tt{b)\: Atmost\: one\: head\: =\:three }$$\tt{cases\: (HT,TH,TT)}$

⠀ ⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

↠$\tt\frac{3}{4}$
