Question

solve tis question please
question 12

Answer 1

since mode = 20

so maximum times will be 20 .

so ,

lembda = 20

Answer 2

for 13 there are 1 terms .
similarly 15 are 3 terms
17-1 terms
18-3 terms
20-3terms
25-3terms
lambda-1 terms
and we know mode is 20
so its obvious that the term which we have to find will be 20 because only the the mode of data can be 20.
