Question

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

$\tiny\boxed{\begin{array}{cc} \: \sf Outcomes & \sf Frequency \\\frac{\qquad \qquad \qquad \qquad}{}&\frac{\qquad \qquad \qquad \qquad}{}& \\\sf H&\sf 90 \\\ \\ \sf T &\sf 60 &\sf \end{array}}$

The probability of getting a head in a trial is :

$\sf{(a)\: \dfrac{1}{2} }$



$\sf{b)\: \dfrac{1}{3} }$


$\sf{c)\: \dfrac{3}{5} }$


$\sf{d)\: none \:of \:these }$​

Answer 1

Step-by-step explanation:

the ans is option B : 1/3..

Answer 2

$\large{\underbrace{\sf{\red{Required\:answer:}}}}$

$\sf{Total \: number \: of \: possible \: outcomes =150}$

$\sf{Number \: of \: heads \: in \: a \: trial = 90}$

$\sf{ P(E) = \large \frac{Number\: of\: favourable}{Total \:Number \:of \:outcomes}}$

$\sf{Probability \: of \: getting \: a \: head = \large \frac{90}{150} }= \large \frac{3}{5}$

$\sf{Hence,\: the\: probability \:of \:getting \:a \:head\: in\: a}$ $\sf{trial\: is\: \large \frac{3}{5}}$

$\sf{\therefore\:Option\:"c"\: is\: correct}$
