Answer 2

36 students bought their lunch from cafeteria.

Explanation:

Given : Total girls = 35

Total boys = 50

To find:How many students bought their lunch from the cafeteria?

Solution:

Probability of boys bought their lunch from cafeteria = 0.44

Since total no. of boys =50

So, no. of boys bought their lunch from cafeteria = 50*0.44

=22

Probability of girls bought their lunch from cafeteria = 0.4

Since total no. of girls =35

So, no. of girls bought their lunch from cafeteria = 35*0.4

=14

So, total no. of students bought their lunch from cafeteria = 22+14 =36

Hence 36 students bought their lunch from cafeteria.
