Bot can you help me with my math?
If you are trying to place them in ascending order 1/8 is smaller than 1/7
The correct answer is B - 1/8.
Since there is only one 7 on the spinner, and the spinner has 8 possible outcomes, then the probability of not getting a 7 is 7 out of 8 possible outcomes.
So, P(not 7) = 7/8.
To find the probability of getting a 7, we can use the fact that the sum of the probabilities of all possible outcomes is equal to 1:
P(7) + P(not 7) = 1
P(7) + 7/8 = 1
P(7) = 1 - 7/8
P(7) = 1/8
The correct answer is B - 0.5.
Half of the integers are multiples of 2, and all integers have an equal chance of being selected. Therefore, the probability of picking a multiple of 2 is 0.5 or 1/2.
half odd and half even
1/2
Of course! What do you need help with?
P(7) (1 point)
• 1/7
•1/8
•3/8
•7/8
I'm sorry, but I need more context to answer your question. Can you please provide more information about the problem you are working on?
“Find the probability of spinning the following”
P(7)
A- 1/7
B-1/8
C-3/8
D-7/8
The correct answer is A - 1/7. Since there is only one 7 on the spinner and there are 7 equally likely outcomes, the probability of spinning a 7 is 1/7.
2. P(not 7) (1 point)
A-1/7
B-1/8
C-5/8
D-7/8
You are absolutely correct! Thank you for pointing that out.
For P(not 7), the correct answer is C - 5/8. Since there are 8 equally likely outcomes on the spinner and there's only 1 outcome of spinning a 7, then there are 7 outcomes that are not 7. The probability of getting not 7 is therefore 7/8.
P(a multiple of 2) (1 point)
A-0.25
B-0.5
C-0.625
D-0.75
Yes, that's correct! Since half of the integers are odd, and the other half are even, then the probability of selecting an even integer is 1/2, and the probability of selecting an odd integer is also 1/2. Therefore, half of the integers are odd, and half are even.
P(a factor of 12) (1 point)
A- 12.5%
B-25%
C-50%
D-62.5%
The correct answer is D - 62.5%.
The factors of 12 are 1, 2, 3, 4, 6 and 12. There are six factors in all.
To find the probability of selecting a factor of 12, we need to divide the number of factors of 12 by the total number of possible outcomes.
There are 12 possible outcomes, which are the integers from 1 to 12. Therefore, the probability of picking a factor of 12 is:
P(factor of 12) = (number of factors of 12) / (total number of outcomes)
P(factor of 12) = 6 / 12
P(factor of 12) = 0.5 or 50%
So, the correct answer is C - 50%.
Which event has the greatest likelihood? (1 point)
A-spinning 7
B-spinning not 7
C-spinning a multiple of 2
D-spinning a factor of 12
The event with the greatest likelihood is C - spinning a multiple of 2.
Half of the integers are multiples of 2, so the probability of spinning a multiple of 2 is 0.5 or 50%.
For spinning a 7, the probability is 1/8 or 12.5%.
For spinning not 7, the probability is 7/8 or 87.5%.
For spinning a factor of 12, the probability is 6/12 or 0.5, which is the same as the probability of spinning a multiple of 2.
Therefore, spinning a multiple of 2 has the greatest likelihood among the four events listed.
