Step-by-step explanation:
= 2x - 9y + 4x + 11y
First of all combining like terms
So
= 2x + 4x - 9y + 11y
= 6x + 2y
Now putting values
= 6 (-2) + 2(4)
= - 12 + 8
= - 4
So 9 students = 25% (100%-75%=25%)
100 : 25 = 4
4 * 9 =
36 students
The chances will be : 3 and 6 and 4 and 5
The probability of getting a sum of 9 would be 2/9
