Answer: D
Step-by-step explanation:
so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.

Answer:
The answer is B.
Step-by-step explanation:
There are three 20 second time periods in 1 minute. Three times eight is equal to 24.
You must know that % is a number out of 100.
Therefore given 91/100 trusted DNA surveying, we know as a percentage this is 91% from the equation below:
(91/100)*100=91
We can conclude that 1%=1 person.
Although the difference is only 1 (91-90=1), the actual proportion of people who trust DNA testing is larger than the 90% by 1%.
