Question

A bag has 30 cards it in. There are 10 red cards, 10 blue cards, and 10 yellow cards. What is the probability that you reach in without looking and pick a red card?

Answer 1

The probability of picking a red card can be calculated by dividing the number of red cards by the total number of cards in the bag:

P(red card) = number of red cards / total number of cards

P(red card) = 10 / 30

P(red card) = 1/3 or approximately 0.333

So the probability of picking a red card is 1/3 or 0.333.
