Answers
Step-by-step explanation:
1). student born in August = 5
total no. of students born = 39
probability (August) = 5/39
2) student born in November = 4
total no. of students born = 39
probability (November) =4/39
3). student born in june = 1
total no. of students born = 39
probability (November) =1/39
4). students born after june = 2+5+3+4+4+4=22
total number of students =39
probability (born after half of the year) =22/39
5). students born in the month having 31 days
=jan +march + may+july+aug+oct+dec
=3+2+5+2+5+4+4=28
total students = 39
probability (born in the month having 31 days)
= 28/39
6). students born in the month having 30 days
=april+june+September+November
=2+1+3+4=10
total students = 39
probability (born in the month having 30 days)
= 10/39
this is the solution of the question.
