Here is your answer
1) 5/8
2) 1/2
3) 1/4
REASON:
P(event)=
Favourable outcomes/Possible outcomes
All possible outcomes are:
1,2,3,4,5,6,7 and 8
No. of possible outcomes= 8
1] Number no more than 5 are:
1,2,3,4 and 5
Favourable outcomes=5
P(a number no more than 5)=5/8
2] All even numbers are:
2,4,6 and 8
Favourable outcomes=4
P(an even number)= 4/8=1/2
3] Numbers less than 3 are:
1 and 2
Favourable outcomes= 2
P(a number less than 3)= 2/8=1/4
[Note:- No more than 5 means a number which is not greater than 5,i.e. 5 must be included]
