[tex]\sf Hello![/tex]
• [tex]\sf Number\: of \:times \:head \:came\: up = 9[/tex]
• [tex]\sf Number \:of \:times \:coin \:is \:flipped = 20[/tex]
[tex]\sf Relative\: frequency\: of \:head \:coming \:up[/tex] :
= [tex]\dfrac{\sf 9}{\sf 20} × \sf 100[/tex] %
= [tex]\sf 9 × 5[/tex]
= [tex]\sf 45[/tex] %
= [tex]\dfrac{\sf 45}{\sf 100}[/tex]
= [tex]\sf 0.45[/tex]
[tex]\sf Hence,[/tex]
[tex]\sf Realtive\: frequency\: of\: head \:coming\: up\: is \:B.\:0.45[/tex]
