Question

cards marked with numbers 13,14,15....60,are placed in a box and mixed thoroughly.one carf is drawn at random from the box.find the probabilitu that number on the card drawn is divisible by 5

Answer 1

probability of getting a card divisible by 5=no. of favourable terms/no. of terms

no.of favourable terms=10
since,5 divides 15,20,25,...,55,60

total no.of terms=48

therefore;probablity=10/48
=5/24
