Answer 2

Given:-

• Cards marked with the numbers 2 to 101 are placed in a box.

To find:-

• Probability of getting a card that bears a number which is a perfect cube.

Solution:-

$:\implies \sf{Total\:Outcomes=100} \\ :\implies\sf{Favourable\:Outcomes=3}\\ \boxed {\frak{8,27,64}} \blue \bigstar$

Using Formula :-

$\boxed {\sf{Probability = \frac{No.of \: favorable \: outcomes}{Total \: no. of \: outcomes}}} \orange \bigstar$

Putting Values:-

$: \implies\sf{\dfrac{3}{100}}$

So,

$\pink\bigstar\boxed{\sf{The Probability of getting a perfect cube is  \frac{3}{100}} }$

$\boxed { \large\boxed{ \sf{\purple{ {Extra \: Information:}}}}}$

Probability :

• It is defined as chances of occuring or happening of an event.
• Probability of an event can never be negative.
• Probability of an event always lies between 0 and 1.

Thank you!
