Each of the letters in the word CALCULATOR are on separate cards, face down on the table. If you pick a card at random, what is the probability that it's letter it's letter will be C or L?
4/10 = 2/5
To determine the probability of picking a card with the letter C or L from the word CALCULATOR, we first need to find out how many cards have the letter C or L.
The word CALCULATOR has 11 letters in total. Among these letters, there are two Cs and one L. So there are a total of 2 + 1 = 3 cards with the letter C or L.
Next, we need to find out the total number of cards. Since each letter is on a separate card, there are 11 cards in total.
Therefore, the probability of picking a card with the letter C or L is equal to the number of cards with C or L divided by the total number of cards:
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 3 / 11
Hence, the probability of picking a card with the letter C or L is 3/11 or approximately 0.27 (rounded to two decimal places).
