Question

Mohini has 15 cards marked with 1 to 15 on it. Which of these is the list of all possible outcomes of getting a card with a number divisible by 3?

Answer 1

Step-by-step explanation:

Sample space (S) = { 1,2,3,4,5,6,7,8,9,10,11,2,13,14,15}

n(S) = 15

Let E be the event of getting an card number which is divisible by 3

E= { 3,6,9,12,15}

n(E) = 5

Probability that the card number is divisible by 3 = no.of favourable outcomes of event E

_______________________________

Total no. of outcomes

= P(E). 5. 1

_____. =. ____ = _____

n(S). 15. 3

1/3 is the probability of getting the card number which is divisible by 3
