Answer 1

Answer :

A coin is tossed 150 times and data about the outcomes is as below :

Head = 90

Tail = 60

The probability of getting a head in a trial is ?

Answer :

Option ( c )

H = 90

Total tossed = 150

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

Probability of Getting a head = $\sf\huge\frac{3}{5}$

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

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

◇ 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

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

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