Question

There are 40 cards in a bag each bears number 1 to 40 one card is drawn at random what is the probabality that card bears number is multiple of 5

Answer 1

Given :

• There are 40 cards in a bag .

To Find :

• Probability of getting a multiple of 5 .

Solution :

$\longmapsto\tt{Total\:Outcomes=40}$

$\longmapsto\tt{Favourable\:Outcomes=8}$

= 5 , 10 , 15 , 20 , 25 , 30 , 35 ,40 .

$\longmapsto\tt\bf{Probability=\frac{No.\:of\:Fav.\:Outcomes}{Total\:No.\:of\:Outcomes}}$

$\longmapsto\tt{\cancel\dfrac{8}{40}}$

$\longmapsto\tt\bf{\dfrac{1}{5}}$

So , The Probabilty of getting a multiple of 5 is 1/5 ...
