Suppose you spin the spinner once. Find the probability.
P(yellow) (1 point)
one-eighth
start fraction 1 over 6 end fraction
one-fourth
one-half
I chose 1/8
That is incorrect. Without knowing the number of sections on the spinner or how many are yellow, it is impossible to determine the probability. More information is needed.
Four Red, Two Blue, One Green, One Yellow
Thank you for providing the additional information.
With four red sections, two blue sections, one green section, and one yellow section, there are a total of 8 sections on the spinner.
The probability of landing on yellow is 1 out of 8, since there is only one yellow section out of 8 total sections.
Therefore, the correct answer is:
P(yellow) = one-eighth
Suppose you spin the spinner once. Find the probability.
There are Four Red, Two Blue, One Green, One Yellow
2. P(red or blue) (1 point)
0
one-fourth
one-half
start fraction 3 over 4 end fraction
I chose 3/4
That is incorrect. To find the probability of spinning red or blue, you need to add the probabilities of spinning red and blue, since they are the two outcomes of interest.
The probability of spinning red is 4 out of 8 (since there are 4 red sections out of 8 total sections), which simplifies to 1/2.
The probability of spinning blue is 2 out of 8 (or 1/4).
To find the probability of spinning red or blue, you add the two probabilities:
P(red or blue) = P(red) + P(blue)
P(red or blue) = 1/2 + 1/4
P(red or blue) = 3/4
Therefore, the correct answer is:
P(red or blue) = 3/4
What is the probability that 1 shopper, selected at random, preferred neither Drink E nor Drink C? (1 point)
thirty-five over forty-one
thirteen over forty-one
twenty-eight over forty-one
thirteen over twenty-eight
I chose twenty-eight over forty-one
That is incorrect.
To find the probability that a shopper preferred neither Drink E nor Drink C, we need to find the number of shoppers who preferred a different drink and divide it by the total number of shoppers.
From the table, we can see that 10 shoppers preferred Drink A, 9 preferred Drink B, 7 preferred Drink D, and 6 preferred Drink F.
The number of shoppers who did not prefer Drink E or Drink C is:
10 + 9 + 7 + 6 = 32
The total number of shoppers is:
10 + 9 + 8 + 7 + 6 + 1 = 41
Therefore, the probability that a shopper preferred neither Drink E nor Drink C is:
P(neither E nor C) = 32/41
So, the correct answer is:
thirty-two over forty-one

3. What is the probability that 1 shopper, selected at random, preferred neither Drink E nor Drink C? (1 point)
thirty-five over forty-one
thirteen over forty-one
twenty-eight over forty-one
thirteen over twenty-eight
I chose twenty-eight over forty-one
That is still incorrect.
To find the probability that a shopper preferred neither Drink E nor Drink C, we need to find the number of shoppers who preferred a different drink and divide it by the total number of shoppers.
From the table, we can see that 10 shoppers preferred Drink A, 15 preferred Drink B, and 3 preferred Drink D.
The number of shoppers who did not prefer Drink E or Drink C is:
10 + 15 + 3 = 28
The total number of shoppers is:
10 + 15 + 7 + 3 + 6 = 41
Therefore, the probability that a shopper preferred neither Drink E nor Drink C is:
P(neither E nor C) = 28/41
So, the correct answer is:
twenty-eight over forty-one
