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 its letter will be C or L
I just counted 4 Cs and Ls, so the prob(picking a C or L)
= 4/10
= 2/5
Oh, I love playing with words! Let's calculate the probability of picking a card with either the letter C or L.
First, we need to determine the total number of different letters in the word CALCULATOR. Here, we have 2 Cs, 2 As, 2 Ls, 1 U, 1 T, 1 O, and 1 R, making a total of 10 different letters.
Now, let's look at our desired outcomes, which are the cards with the letter C or L. We have 2 Cs and 2 Ls, so a total of 4 cards that meet our criteria.
Therefore, the probability of picking a card with either the letter C or L is 4/10, or simplifying it, 2/5.
So, your chance of picking a card with a C or L is 2/5 or about 40%. But don't worry, even if you don't pick a C or L, there are still plenty of other letters to choose from to have some fun with the other cards!
To calculate the probability, we need to determine the number of favorable outcomes (cards with the letters C or L) and the total number of possible outcomes.
The word "CALCULATOR" has 1 letter C and 2 letter L's, so there are a total of 1 + 2 = 3 favorable outcomes.
Since there are a total of 10 letters in the word "CALCULATOR," the total number of possible outcomes is 10.
Therefore, the probability of selecting a card with the letter C or L is 3/10 or 0.3, which can also be expressed as a 30% probability.
To find the probability of picking a card with the letter C or L, you first need to determine the number of favorable outcomes (cards with the letter C or L) and the number of possible outcomes (total number of cards).
Step 1: Determine the number of favorable outcomes:
In the word CALCULATOR, there are 2 Cs and 1 L. So, there are a total of 2 + 1 = 3 favorable outcomes (C or L).
Step 2: Determine the number of possible outcomes:
Since there are 10 letters in the word "CALCULATOR," there are 10 possible outcomes (total number of cards).
Step 3: Calculate the probability:
To calculate the probability, divide the number of favorable outcomes by the number of possible outcomes:
Probability = Number of Favorable Outcomes / Number of Possible Outcomes
Probability = 3/10
Therefore, the probability of picking a card with the letter C or L is 3/10 or 0.3 (30%).
