प्रश्न
Nine cards (identical in all respects) are numbered 2 to 10. A card is selected from them at random. Find the probability that the card selected will be an even number and a multiple of 3.
उत्तर
There are 9 cards from which one card is drawn.
Total number of elementary events = n(S) = 9
From numbers 2 to 10, there is one number which is an even number as well as multiple of 3 i.e. 6
Favorable number of events = n(E) = 1
Probability of selecting a card with a number which is an even number as well as multiple of 3 = `(n(E))/(n(S)) = 1/9`
