Answer:
0.0025 = 0.25%
Step-by-step explanation:
First we need to find how many people don't have flue shots.
28% of 50 is equal to 0.28 * 50 = 14 people.
If 14 people have flue shots, we have 50 - 14 = 36 people that don't have flue shots.
Now, to solve this problem, the probability will be the cases where we have a group of people that don't have flue shots (that is, a combination of 36 choose 15) over the total cases (combination of 50 choose 15):
C(36,15) / C(50,15) = (36!/15!*21!) / (50!/15!*35!) = 0.0025 = 0.25%
Answer:
A. 13.5ft
Step-by-step explanation:
If the ratio is 90:3 and there are 4 groups of 3 in 12, then the ratio would then be 450:12, leaving you with 450 as the answer. Hope I helped
Answer:
0.0825
Step-by-step explanation:
33/400=0.0825
1/4 =non chocolate bar
3/4 = chocolate bar
45 ÷ 3 = 15
So 1/4 = 15 candy bars
And 1/5 candy bars contained nuts...
45 x 1/5 = 9 chocolate bars contained nuts
The answer is ...
15 non chocolate bars
And
9 chocolate candy bars contained nuts
