Question

Daniel took 12 index cards and wrote the number 1 through 12 on them 1 number of each card. he then collected the cards, shuffled them, and drew one card from the stack. what is the probability that the number on the card is greater than 0

Answer 1

We have 12 cards, each one with a different number, so the probability of each card being picked is 1/12.

Since all these cards have numbers that are greater than 0, all the 12 cards are correct options to being picked.

Adding the probability of all 12 cards, we have 12/12, that is, 1 or 100%.

So the probability of picking a card with a number greater than 0 is 1 or 100% (that is, every card has a number greater than 0).
