Cards marked with numbers 1,2,3......40 are placed in a box and mixed thoroughly . One card is drawn at random from the box . Find the probability that the number on the drawn card is divisible by 3 and 5.

Total numbers= 40
Numbers divisible by 3 and 5 are 15, 30

P(getting card with number divisible by 3 and 5) = 240 = 120

  • 3

total outcome = 40

numbers divisible by 3 and 5 are: 3 5 6 9 10 12 15 18 20 21 24 25 27 30 33 35 36 39 40

total numbers = 19

P( numbers divisible by 3 or 5)=19/40

  • -3

total outcome = 40

numbers divisible by 3 and 5 are: 3 5 6 9 10 12 15 18 20 21 24 25 27 30 33 35 36 39 40

total numbers = 19

P( numbers divisible by 3 or 5)=19/40

  • -3

total number of pssible outcomes=40

numbers which are divsible by 3 and 5=15,30=2

therefore p(numbers which are divisible by 3 and 5)=2/40 i.e 1/20
