   Question

   Two balanced dice are rolled. Define the stochastic variable X is the sum of the eyes that come up, so we have the following probability with different values of X:

   ——– —— — —- — —— — — — —- —- —— X 2 3 43 5 6 7 8 9 10 11 12 Odds 1/36 ? ? ? 5/36 ? ? ? ? ? 1/36 ——– —— — —- — —— — — — —- —- ——

   What is that probability of X = 10?

   
   
   1. TRUE: 3/36
   2. FALSE: 4/36
   3. FALSE: 5/36
   4. FALSE: 6/36
   
   
   1. 3/36: Correct
   2. 4/36: Incorrect
   3. 5/36: Incorrect
   4. 6/36: Incorrect
