If the chances that Sonu, Monu, Mahesh can solve a problem are what is the probability that given problem can be solved if they all try?

• 
  probability of problem solving by sonu,monu and mahesh each are 1/3
  probability of problem not being solved by sonu,monu and mahesh each are 2/3
  the problem is solved if
  1. one of three solves the problem
  so, probability in this case= 3*(1/3)(2/3)(2/3)
  2. two of them solve the problem
  so, probability in this case= 3*(1/3)(1/3)(2/3)
  3. all three solve the problem
  so, probability in this case= (1/3)(1/3)(1/3)
  so,the required probability= (4/9)+(2/9)+(1/27)= 19/27.
