a n b throw a dice probability that a's throw is not greater than b
Read Solution (Total 8)
-
- total no of cases- 36
favourable cases:15
(2,1)(3,1)(4,1)(5,1)(6,1)
(3,2)(4,2)(5,2)(6,2)
(4,3)(5,3)(6,3)
(5,4)(6,4)
(6,5)
the p(a throw is greater than b)= 15/36
s0 the p(a throw is not greater than b)=1-(15/36)=21/36 ans - 11 years agoHelpfull: Yes(25) No(2)
- A's throw throw could be greater than B by following ways
2,1 3,2 3,1 4,3 4,2 4,1 5,4 5,3 5,2 5,1 6,5, 6,4, 6,3 6,2, 6,1
So 15 possibles out comes
Probability is 15/36 or 5/12
Probability of failure 1-p
so 1-5/12
= 7/12

- total no .of possibilities =36
among them 6 pairs are equal and remaining combinations = 30
among them half have first one greater than second = 15
probability is=15/36=5/12 - 11 years agoHelpfull: Yes(1) No(1)
- If a's value is 1 means there may be a chance of b's value is greater than a's like 2,3,4,5,6
Like this the probability is 15 - 11 years agoHelpfull: Yes(0) No(5)
- sample space=6*6=36
now favorable cases:
1)when b's dice show 6,a's dice has 5 chances for a - 11 years agoHelpfull: Yes(0) No(1)
- a
- 11 years agoHelpfull: Yes(0) No(0)
- we are throughing 6 dice total outputs 6^2=36
15 are a>b; 15 are a - 11 years agoHelpfull: Yes(0) No(0)
