Question

A bag contains 10 cards numbered 1 through 10. A card is randomly chosen from the bag. What is the probability that the card has a multiple of 3 on it

Answer 1

less likely as there are only 3 numbers with a multiple 3 6 and 9 but there are more numbers which are not 1 2 4 5 7 8 10

Answer 2

Answer: 3/10

Explanation:

A bag contains 10 cards numbered 1 through 10. That means the cards are numbered 1,2,3,4,5,6,7,8,9 and 10.

The multiples of 3 are numbers that are evenly divided by 3. These are 3,6 and 9 in the cards. There are 3 multiple of 3 from 1 to 10.

Probability that the card has a multiple of 3 on it will now be the number of cards with a multiple of 3 divided by the total number of cards. This will give:

= 3/10
