Question

Cards bearing numbers 3 to 20 are placed in a bag and mixed thoroughly . A card is taken out from the bag at random . What is the probability that the numbers on the card taken out is a composite number

Answer 1

Total no. of cards=18

Composite no. are 4, 6,8,9,10,12,14,15,16,18,20. There are 11 composite no.

So to find probability formula is :

$\frac{no. \: of \: outcomes}{total \: no. \: of \: outcomes}$

So probability of getting composite no. is :

$\frac{11}{18}$
