posledela

\huge \underline\text {Hello There!!}

<h3><u>Given</u></h3>

Rolled A six-sided dice.

<h3><u>To </u><u>Find </u></h3>

P(Prime) as percentage

<h3><u>Solution</u></h3>

Total Possible Outcomes= 1, 2, 3, 4, 5, 6.

So, No. of possible Outcomes= 6

Prime number of the dice= 2, 3, 5

So, No. of favorable outcomes of Prime number= 3

<h3><u>We Know,</u></h3>

\text{Probability of an event= }

\frac{ \text{favorable no. of outcome}}{ \text{total no. of outcome}}  \times 100

\text{Percentage of Probability getting P(Prime) number on face of dice} =

\frac{3}{6}  \times 100 \\   \\ =  \cancel \frac{3}{6}  \times 100 \\  \\  =  \frac{1}{ \cancel2}  \times  \cancel{100} \\  \\  = 50\%

\therefore \% \text{ Probability of getting prime number is  \red{50}   \red\%}
