Question

A card numbered from 1 to 25 at a random find the probability that selected card which is a Multiple of 3

Answer 1

$\large{\underline{\underline{\sf{Given :}}}}$

• Cards from 1 - 25 are drawn randomly

$\large{\underline{\underline{\sf{To\: Find :}}}}$

• Probability of picking a card with multiple of 3.

$\large{\underline{\underline{\sf{Formula :}}}}$

$\small{\boxed{\sf{\dfrac{Favourable\: outcomes}{Total \: outcomes}}}}$

$\large{\underline{\underline{\sf{Solution :}}}}$

• Favourable outcome :

Favourable outcome is the term that is used to define the outcome which we want in order to check out the probability. Here we are asked to find the multiples of 3 which are found between 1 - 25.

There are 8 such numbers.

So here the favourable outcome is 8.

• Total number of outcomes :

Total numberof outcomes is the term used to define the highest possibility of outcomes one can get. Here the highest possibility is 25 . So the total outcomes is 25.

Now let's put up the values in the formula :

$\small{\longrightarrow{\sf{\dfrac{8}{25}}}}$

$\small{\longrightarrow{\sf{\cancel{\dfrac{8}{25}}\implies 0.32}}}$

Probability of picking a card with multiple of 3 : 0.32
