I need some help with a few multiple choice math questions here's one:
The two-way table shows the number of students in a class who like mathematics and/or science.
Like Mathematics
Do Not Like Mathematics
Total
Like Science
18
?
38
Do Not Like Science
16
6
32
Total
34
26
70
What is the missing number in the table?
10
12
20
56
The total should equal how many like and do not like science. Since there are 26 total in that row, and 6 that do not like science, that leaves 20 that do like science. 20 should be the missing number.
