Eric throws 2 dice,and his score is the sum of the values shown.Sandra throws one dice and her score is the square of the value shown. what is the probabilty that Sandras score will be strictly higher than Erics score??
Read Solution (Total 10)
-
- sandra score can be like 1,4,9,16,25,36
eric score less then 1-->0
eric score less then 4=(1,1),(1,2)(2,1)-->3
eric score less then 9 are (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)(4,1)(4,2)(4,3)(4,4)(5,1)(5,2)(5,3)(6,1)(6,2)-->26
eric score will always be less then 16--->36
eric score will always be less then 25--->36
eric score will always be less then 36--->36
total favorable outcomes=3+26+36+36+36=137
total possible outcomes=216(36*6)
probability=137/216

- 137/216 is the answer
- 10 years agoHelpfull: Yes(2) No(5)
- 137/216=0.634
- 10 years agoHelpfull: Yes(1) No(4)
- please explain the logic
- 10 years agoHelpfull: Yes(1) No(1)
- no. of ways sandra score will be higher strictly= 3+26+36*3=137 ways
total no. of ways= 36*6=216
probability =137/216 - 10 years agoHelpfull: Yes(1) No(2)
- plz explain clerly

- can anyone send me the latest verbal question of tcs.........send it on my mail priyankagulhane21@gmail.com

- max. possible sum of two no. can be 12 thn hw ths outcomes has come
- 10 years agoHelpfull: Yes(0) No(1)
- Required probability= favourable outcomes/total outcomes
= (3+26+36+36+36)/(216)
= 137/216 - 10 years agoHelpfull: Yes(0) No(0)
