Answer:
11+12+13+14=50
Step-by-step explanation:
Just estimate. We know that 15 times 4 = 60, so it has to be less than that. We know that 10 times 4 is 40, so it has to be in that range. Just do trial and error to find the exact answer. I'm editing this now and I realized that I didn't answer the question. I don't know how to write the equation using N but the first integer is 11.
Answer:
156 students
Step-by-step explanation:
From the above question:
The formula for the number of students offering only one subject is given as:
n(Biology OR History OR Mathematics) =n(Biology) + n(History) +n(Mathematics) - n(History and Biology) - n(History and Mathematics) - n(Biology and Mathematics) + n(Biology and History and Mathematics)
= (52+60+96)-(21+22+16)+(7)
= 208 - 59 + 7
= 156 students
