Answer:

The answer is below

Step-by-step explanation:

a) The number of pupils who scored more than 7 in a test = pupils who shored  8 + pupils who shored 9 + pupils who shored 10

The number of pupils who scored more than 7 in a test = 7 + 3 + 1 = 11 pupils

b) Total number of pupils = pupils who shored  0 + pupils who shored 1 + pupils who shored 2 + . . . + pupils who shored 9 + pupils who shored 10

Total number of pupils = 0 + 1 + 4 + 0 + 0 + 8 + 0 + 2 + 7 + 3 + 1 = 26 pupils

c) It is assumed that nobody scored either 0 or 3 or 4 or 6. Also the highest mark was assumed to be 10
