-
- ans-(1/2) option no.1
total no.of chances=n(s)=6.....i.e.,{1,2,3,4,5,6}
required numbers={1,2,3}.....i.e.,n(e)=3
so probability=n(e)/n(s)=3/6=1/2 - 9 years agoHelpfull: Yes(12) No(1)
- It is not a elitmus level question.....such type of question can be ask in amcat...
answer- 1/2.... - 9 years agoHelpfull: Yes(3) No(1)
- less than 4 are 1,2,3
probability=3/6=1/2 - 9 years agoHelpfull: Yes(1) No(0)
- 1/6+1/6+1/6=1/2
- 9 years agoHelpfull: Yes(0) No(0)
- 1 die has 6 numbers 1 2 3 4 5 6
so the probability of getting a number less than 4 is 3/6=1/2 - 9 years agoHelpfull: Yes(0) No(0)
- 1 ; 3/6=1/2
- 9 years agoHelpfull: Yes(0) No(0)
- ans: 1/2
there are 3 numbers that are less than 4 out of 6.. so its probability is 1/2 - 9 years agoHelpfull: Yes(0) No(0)
- how this question can be asked in elitmus?
even this is so easy that this can't be asked in CBSE.. lol - 9 years agoHelpfull: Yes(0) No(0)
- 1,2,3=3
total=6
3/6=1/2 - 9 years agoHelpfull: Yes(0) No(0)
- Ans:1/2

- 1/2
bcoz 1,2,3 are less then 4
so, 3/6
=1/2 - 8 years agoHelpfull: Yes(0) No(0)
- No. Of Favourable events is 1,2,3 i.e =3
Total no. Of events =6
So P (e)= 3/6=1/2. - 7 years agoHelpfull: Yes(0) No(0)
- Probability of getting a number less than 4 = 3/6=1/2
- 4 years agoHelpfull: Yes(0) No(0)
- The probability of getting a number less than 4,
we have 3 possibilities,
either 1, 2 or 3
so we have n= 3
i.e 3/6 = 1/2 - 3 years agoHelpfull: Yes(0) No(0)
