plz help
Dear LovelyCaity
Hey! Let's figure it out. So first let's count how many numbers we have.
1: 8
2: 6
3: 7
Now add. 8+6+7= 21.
Let's look at the question now.
It's asking, what are my chances of landing on a 1?
Well, since we have 8 1's our probability would be 8/21, or B.
Sincerely,

To find the probability of landing on a 1, we need to count the number of times a 1 appears on the spinner and divide it by the total number of spins.
From the given results, we can see that the number 1 appears 8 times.
To find the total number of spins, count the total number of results, which is 21.
Therefore, P(1) = 8/21.
So, the correct answer is B. 8/21.
To find the probability of an event, you need to compare the number of favorable outcomes to the total number of possible outcomes. In this case, we need to determine the number of times the number 1 appears on the spinner and divide it by the total number of spins. Let's go step by step:
Step 1: Count the number of times the number 1 appears on the spinner. From the provided results, we can see that the number 1 appears 7 times.
Step 2: Count the total number of spins. From the provided results, we can see that the spinner was spun 20 times.
Step 3: Divide the number of times the number 1 appears by the total number of spins. In this case, it would be 7/20.
Therefore, the probability of landing on 1, P(1), is 7/20.
However, none of the options given match 7/20. Let's simplify the fraction:
7/20 can be reduced to 7/20 * 1/5 = 7/100, which is not one of the options given.
Given the options, none of them represent the correct probability of landing on 1 based on the provided data. It is possible that there was a mistake or missing information in the question or answer choices.
