To work out the mean you add them all up and divide by how many numbers there are:
31+ 28 + 30 + 31 = 120 
120 / 4 = 30

to work out the median you order the  numbers and then find the middle value
28 30 31 31
therefore the median is 30.5

to find the mode you look for the most common number
which is 31

hope this helps you

Easy!
You take the total number of students (55) then you remove the people that only like math and remove the people that only like English and remove the people that like none of them and what’s left is how many like both subjects.

55-15-18-5=17 students that like both subjects!
