Solution:

To solve this problem, we will use the principle of inclusion and exclusion.

Total Complaints Received = n(M) + n(F) + n(S) - n(MFS) + n(MSF) + n(FSOM)

Using the given values, we get:

Total Complaints Received = 110 + 55 + 67 - 20 + 11 + 16 = 239

Complaints About All Three

To find the number of complaints about all three (MFS), we subtract the sum of complaints about two (MSF and FSOM) from the total complaints received:

n(MFS) = Total Complaints Received - n(MSF) - n(FSOM)
n(MFS) = 239 - 11 - 16 = 212

Therefore, the number of complaints about all three is 20.

Answer: Option (a) 6

Complaints About Two or More Than Two

To find the number of complaints about two or more than two, we need to add the complaints about two and subtract the complaints about all three from it:

n(Two or More) = n(MF) + n(MS) + n(FS) - n(MFS)
n(Two or More) = 110 + 55 + 67 - 20 = 212

However, we have already calculated the value of n(MFS) to be 20. Therefore, we need to subtract it from the above value:

n(Two or More) = 212 - 20 = 192

Therefore, the number of complaints about two or more than two is 192.

Answer: Option (c) 35.

Conclusion:

The number of complaints about all three is 20, and the number of complaints about two or more than two is 192.
