1. Riley writes the letters C-A-L-I-F-O-R-N-I-A on cards and then places the cards in a hat. What is the probability of picking an L?
A: 1/10
B:2/10
C:1/9
Please, help me!
There's one L and 10 letters.
What do you think the answer is?
1/10? ;o;
Yes. 1/10
How about
A bag contains 6 green marbles and 5 pink marbles. You select a marble at random. What are the ODDS in favor of picking a green marble?
A: 1:6
B: 5:6
C: 6:5
And your answer is?
My answer was B, but I'm not too sure about it.
But your problem states there are 6 green marbles. Why did you choose B with only 5 green marbles?
I thought the 5 was the pink marbles, not the 6 marbles, so it's going to be C? 6:5, since there are 6 marbles and 5 pink marbles?
Yes, C.
To find the probability of picking an L from the hat, we need to know two pieces of information: the number of L's in the set of cards and the total number of cards in the set.
Step 1: Count the number of L's in the set.
In the word "CALIFORNIA," there is only one L.
Step 2: Count the total number of cards in the set.
The word "CALIFORNIA" has 10 letters, so there are 10 cards in total.
Step 3: Calculate the probability.
The probability is the number of favorable outcomes (picking an L) divided by the total number of possible outcomes (all the cards in the set).
Favorable outcomes: There is only one L card.
Total possible outcomes: There are 10 cards in total.
So, the probability of picking an L is 1/10.
Therefore, the correct answer is A: 1/10.
