Probability
two dice are thrown. find the probability of getting a multiple of 3 of 4 as the sum
Read Solution (Total 12)
-
- 20/36=5/9
(1,2),(1,3),(1,5),(2,1)(2,2)(2,4)(2,6)(3,1)(3,3)(3,5)(3,6)(4,2)(4,4)(4,5)(5,1)(5,3)(5,4)(6,2)(6,3)(6,6) as its some is multiple of 3 or 4 - 9 years agoHelpfull: Yes(39) No(0)
- Their sum can be 3,4,6,8,9,12
For two dice, any number from 2 to 7 can be get in (n-1) ways and any number from 8 to 12 can be get in (13 - n) ways.
Then possible ways are 2 + 3 + 5 + 5 + 4 + 1 = 20 possible cases.
So probability is (20/36)=(5/9) - 8 years agoHelpfull: Yes(4) No(1)
- (1,2)(1,3)(1,5)
(2,1)(2,2)(2,4)(2,8)
(3,1)(3,3)(3,5)(3,6)
(4,2)(4,4)(4,5)
(5,1)(5,3)(5,4)
(6,2)(6,3)(6,6)
so total outcomes will be 20
probablity=20/36=5/9 - 8 years agoHelpfull: Yes(3) No(0)
- 23/36
Solution - 9 years agoHelpfull: Yes(1) No(9)
- Probability – Sample space for two dice (outcomes):
(1,1)(1,2)(1,3)(1,4)(1,5)(1,6)
(2,1)(2,2)(2,3)(2,4)(2,5)(2,6)
(3,1)(3,2)(3,3)(3,4)(3,5)(3,6)
(4,1)(4,2)(4,3)(4,4)(4,5)(4,6)
(5,1)(5,2)(5,3)(5,4)(5,5)(5,6)
(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)
multiple of 3 of 4 as the sum =
- 9 years agoHelpfull: Yes(1) No(6)
- 1/2
....18/36
- 9 years agoHelpfull: Yes(0) No(11)
- 18/36=1/2 multiple of 3 or 4 is 18
and total no of throws is 36 - 9 years agoHelpfull: Yes(0) No(6)
- 5= (1,2),(2,1),(1,3),(3,1),(2,2)
5/36 - 9 years agoHelpfull: Yes(0) No(3)
- thank u abhineet kumar
- 9 years agoHelpfull: Yes(0) No(0)
- 2/12 + 3/12 = 5/12
Is it correct? - 9 years agoHelpfull: Yes(0) No(2)
- As I think
That in Question two die should be multiple of 3 and which should 4 as a addition
So
Number will be : ( 2,4) , (5,4)
Then 2/36
Will gives 1/18 - 5 years agoHelpfull: Yes(0) No(0)
- 20/36=5/9
(1,2),(1,3),(1,5),(2,1)(2,2)(2,4)(2,6)(3,1)(3,3)(3,5)(3,6)(4,2)(4,4)(4,5)(5,1)(5,3)(5,4)(6,2)(6,3)(6,6) as its some is multiple of 3 or 4 - 1 year agoHelpfull: Yes(0) No(0)
