$\Large\fbox\red{❥Answer:\:Option \: (c)}$

$\small{\underline{\mathtt{\orange{❥Given}}}}$

◇ Head = 90

◇ Tail = 60

$\small{\underline{\mathtt{\orange{❥To \:Find}}}}$

◇ The probability of getting a head in a trial

$\Large{\underline{\mathtt{\green{❥Solution}}}}$

H = 90

Total tossed = 150

$\sf \frac{ \cancel{90}}{ \cancel{150}} = \frac{ \cancel{18}}{ \cancel{30}}= \frac{ \cancel6}{ \cancel{10} }= \frac{3}{5}$

$∴Option \: (c) \: \frac{3}{5} is \: your \: answer$
