plz solve it..........​

Answer 1

Answer:

this information is insufficient

Step-by-step explanation:

probability of students say 'yes ' is 3/4 and probability of students say 'No' is 1/4 (1-3/4).

now, 50% student present minimum.=15

minimum absent student is 2.

number of present student can be 16 to 28

for this student probability of answer 'yes' can be

12/16, 15/20, 18/24, 21/28 all are 3/4

this is possible present student 16,20,24,28 anything.

so, given information is insufficient.

if some information given about absent student answering 'Yes' or 'No' than we can find.
