Answer 2

(i) total number of students in class =38

the number of students who's weight is between 36kg to 45kg =19

probability of students who's weight is between 36kg to 45kg =

$\frac{ number \: of \:student \: whose \: weight \: is \: between \: 36kg \: to \: 45g}{total \: number \: of \: student \: in \: class}$

$= \frac{19}{38}$

=1/2

(ii) the event which has 0 probability = the weight of students between 26 to 30

and

the event which has 1 probability=

the weight of student between 51 to 55

plzz mark me as brainliest.......
