Out of 200 students in a class, 150 like football and 120 like cricket. If the number of students who like
cricket only is one third of the number of students
who like football only, then using Venn diagram
find the number of students who like. (i) both games
(ii) football only (iii) none of these games.​

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
