Detailed Solution

According to the question, we have to find the probability of throwing a number greater than 2 with a fair die.
The possible set of values that can be obtained on a die is {1,2,3,4,5,6}   .
Thus, the total possible outcomes is = 6
Number of favorable outcomes {3,4,5,6}   = 4
So the probability of getting a number greater than 2 is given as,
P(E)= no. of favorable outcomes   total number of outcomes   
  P E = 4 6 P E = 2 3  
So, the probability of getting a number greater than 2 on the die is given by 2 3   .
Hence, the correct option is 2.
