The probability of a spinner landing on yellow is 1/4 what does 3/4 represent? A. yellow B. blue C. yellow D. purple and blue
D. Purple and blue.
If the probability of landing on yellow is 1/4, then the probability of NOT landing on yellow (landing on any of the other colors) is 3/4. Therefore, 3/4 represents the combined probability of landing on purple and/or blue.

These are all the possible outcomes of Marty going to one movie on one day, where he can choose between a comedy or an action movie and can go either on Friday or Saturday.
a health study of $540 adults found that only 7 and 20 adults get enough sleep each night based on the results of the sample how many adults got enough sleep
A. 27 B. 35 c. 89 D.202
We can start by setting up a proportion where the number of adults who get enough sleep is compared to the total number of adults in the population:
x / 540 = 7/20
To solve for x, we can cross-multiply to get:
20x = 7 * 540
20x = 3780
x = 3780 / 20
x = 189
Therefore, based on the results of the sample, 189 adults got enough sleep. None of the answer choices given match this result, so it's possible that there was an error in the question or answer choices.
Two coins are flipped what is the probability that both coins land on heads type your answer is a fraction
The probability of getting heads on one coin flip is 1/2.
To find the probability of getting heads on both coin flips, we multiply the probability of each event. So:
P(heads on first coin AND heads on second coin) = P(heads on first coin) * P(heads on second coin)
P(heads on first coin AND heads on second coin) = (1/2) * (1/2)
P(heads on first coin AND heads on second coin) = 1/4
Therefore, the probability of both coins landing on heads is 1/4.
Daniel is selecting a sock from his drawer at random. If Daniel dose this 60 times, what is reasonable prediction for the number of times he will get a striped sock?
We can't provide an exact prediction of the number of times Daniel will get a striped sock, but we can provide a reasonable prediction based on probability.
Let's say that Daniel's drawer has 20 socks in it and 4 of those socks are striped. Then the probability of him selecting a striped sock at random is 4/20 or 1/5.
If he selects a sock 60 times, we can predict that he will get a striped sock about 1/5 of the time. To find out exactly how many times that would be, we multiply the probability of getting a striped sock by the number of times he selects a sock:
(1/5) * 60 = 12
Therefore, a reasonable prediction is that Daniel will get a striped sock about 12 times out of the 60 times he selects a sock. However, if the drawer has a different number of socks or a different number of striped socks, this prediction will change.
Daniel is selecting a sock from his drawer at random. If Daniel dose this 60 times, what is reasonable prediction for the number of times he will get a striped sock?
there are 6 white and 2 striped socks
