You spin the spinner twice and record the sum of the numbers you get. What is the probability that the sum is 5? A.) 1/3 B.) 1/9 C.) 2/9 D. 0
I choose A I think its correct but want to make sure. Thanks!!
All answers for the Compound Probability Unit Test for Connections:
1: There are 16 possible outcomes, all outcomes are equally likely
2: 2/9
3: 2/3
4: extended response
5: extended response
6: tossing five coins, spinning a spinner with 2 equal parts 5 times
7: extended response
8: a fair coin flipped three times, a spinner with two equal sections spun three times
9: flipping a coin 4 times
10: roll a six-sided number cube two times
11: a spinner with 4 equal sections
12: extended response
The answer is c. 2/9
The answer is ccccccccc
B thats what the guy reiny said
Thanks this makes sense!!!
Its 2/9
Yes, you are correct. The answer to question 2 is 2/9.
To find the probability of getting a sum of 5 when spinning the spinner twice, we need to first determine all the possible outcomes.
Let's say the spinner has numbers 1, 2, 3, 4, 5, and 6 on it.
To get a sum of 5, the possible outcomes are:
1 + 4
2 + 3
3 + 2
4 + 1
So, there are four possible outcomes that result in a sum of 5.
Now, let's find the total number of possible outcomes when spinning the spinner twice. Since each spin has 6 possible outcomes, the total number of possible outcomes for two spins will be 6 multiplied by 6, which is 36.
To calculate the probability, we divide the number of favorable outcomes (getting a sum of 5, which is 4) by the total number of possible outcomes (which is 36).
Therefore, the probability of getting a sum of 5 is 4/36, which simplifies to 1/9.
So, your choice of A.) 1/3 is incorrect. The correct answer is B.) 1/9.
I hope this helps clarify your answer. Let me know if you have any other questions!
this is to hard for my brain.
To get a sum of five, you need
14 , 23, 32, or 41
so there are 4 out of the 36 possible outcomes
4/36 = 1/9
analysis:
create a chart with 6 colums and 6 rows, numbering them from 1-6
fill in the sum of row and column
note the sum of 5 results, there are 4 of them out of the total of 36 possible sums
