Answer:
1. 45
2. 9
3. 11
4. 17
Explanation:
Given the following:
28 checked H
26 checked C
14 checked D
8 checked H and C
4 checked H and D
3 checked C and D
2 checked all.
Hence N(H) = 28
N(C) = 26
N(D) = 14
N(H U C) = 8
N(H U D) = 4
N(C U D) = 3
N(H U C U D) = 2
We also know that
Total = N(H) + N(C) + N(D) - N(H U C) - N(H U D) - N(C U D) + N(H U C U D)
Substituting the given values, we obtain
Total = 55
1. Students that didn't check any box = 100 - 55 = 45 students
2. Students who checked exactly two box
= N(H U C) + N(H U D) + N(C U D) - 3N(H U C U D) (from probability theorem)
Substituting the values, we have 8 + 4 + 3 - 6 = 9 students
3. Students who checked atleast two box =
The people who have checked all three are needed to be calculated once. Earlier, we subtracted them thrice so we add one time
N(H U C) + N(H U D) + N(C U D) - 2N(H U C U D) = 8 + 4 + 3 - 4 = 11 students
4. Given N(C) = 26
We subtract N(CUD) and N(HUC) as they have checked another apart from club.
26 -8 - 3 = 15
Now we could notice we have subtracted N(HUCUD) twice in both categories, so we add one time to neutralise
15 + 2 = 17
Hence N(only C) = 17 students.
It would depend on the movie and the theater policy.....
Hope this helps have a good day

Answer:
<em>All About The Space. Since many websites use certain image formats to save space and bandwidth, different types of files are used. the most widely used on sites are JPG (JPEG) or GIF images. These are done to save space. And in some cases certain sizes may stretch the image/photo to where it looks silly or bad, that's why there are also small versions.</em>
Explanation:
Different sizes for different occasions
