Q. Two diced are tossed the probability that the total score is a prime number?

• possible outcomes for prime number = 2,3,5,7,11
  so for 2=(1,1)= only 1 possible combination
  for 3= (2,1) (1,2) = 2 combinations
  for 5= (2,3) (3,2)(4,1) (1,4) = 4 combinations
  for 7= (6,1) (1,6) (2,5) (5,2) (3,4) (4,3) = 6 combinations
  for 11= (6,1),(1,6) = 2 combinations
  total = 15
  possible total outcomes = 6 x 6 = 36
  so probability of getting a toatal of prime number = 15/36
  =5/12 ans

• probability of prime numbers is: 16/36.
  prime numbers 2,3,5,7,11.
  possibilities are (1,1),(1,1),(2,1),(1,2),(2,3),(3,2),(3,4),(4,3),(2,5),(5,2),(6,1),(1,6),(4,1),(1,4),(5,6),(6,5).
  the answer is = 16/36

  prime numbr in 2,3,5,7,11 and and thr combination in two dice then i get 5/12

• answer is 5/12
• 9 years agoHelpfull: Yes(0) No(0)
• sum shoul be prime
  so, prob.= 15/36

• ans- 5/12
  the sets producing prime nos. are
  1,1 1,2 1,4 1,6
  2,1 2,3 2,5
  3,2 3,4
  4,1 4,3
  5,2 5,6
  6,1 6,5
  these are 15 sets.
  total no. of sets = 6 X 6 =36
  prob. = 15/36 = 5/12
