Probability of getting a total of 5 when 2 dice are thrown
Read Solution (Total 4)
-
- u ll get 5 n only these cases
(2,3),(3,2),(1,4),(4,1) n total no of cases are 36 so 4/36=1/9 - 10 years agoHelpfull: Yes(7) No(0)
- 1/9.... because, there are 4 possibilities of getting a sum of five..... 1)1+4
2)4+1.. 3)2+3... 4)3+2 out of a total probability of 36.... therefore, 4/36=1/9 - 10 years agoHelpfull: Yes(2) No(0)
- 1/9...(1,4),(2,3),(3,2),(4,1)
hence 4/36 = 1/9 - 10 years agoHelpfull: Yes(1) No(0)
- when two dice are thrown n(s)=36 i.e{(1,1),(1,2),(2,1),(1,3),(3,1)etc..}
event of getting total 5 ={(1,4),(4,1),(2,3),(3,2)}
so P(e)=4/36
=2/18 - 10 years agoHelpfull: Yes(0) No(0)
