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?
4/10 = 2/5
2/9
Well, if you're looking for a little probability play, here's what we can do. Let's count the cards that have either a C or an L.
In the word CALCULATOR, there is one C and two L's. So that's a total of three favorable outcomes (C and both L's) out of the total number of cards, which is 10.
So, the probability of picking a card with either a C or an L is 3/10.
But let's be real here, with all those numbers and letters flying around, it's like doing acrobatics with a calculator!
To find the probability, we need to calculate the number of favorable outcomes (cards with the letter C or L) and divide it by the total number of possible outcomes (all the cards).
Step 1: Count the number of favorable outcomes:
There are two cards with the letter C and one card with the letter L. So, the number of favorable outcomes is 2 (C cards) + 1 (L card) = 3.
Step 2: Count the total number of possible outcomes:
The total number of cards is equal to the number of letters in the word CALCULATOR, which is 10.
Step 3: Calculate the probability:
Probability = (Number of Favorable Outcomes) / (Total 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%).
To find the probability, we need to calculate the number of favorable outcomes and the total number of possible outcomes.
In this case, we have the word "CALCULATOR" with separate cards for each letter face down. The favorable outcomes are when we pick a card with the letter "C" or the letter "L". To find the number of favorable outcomes, we count the occurrences of "C" and "L" in the word, which are 2.
The total number of possible outcomes is the total number of cards or letters in the word "CALCULATOR", which is 10.
Therefore, the probability of picking a card with the letter "C" or the letter "L" is 2/10, which simplifies to 1/5 or 0.2.
