Step by Step Explanation:
  1. Let us assume S, E and P are the sample space, event, and probability, respectively, of getting a number more than 2 by throwing a dice.
    S = {1, 2, 3, 4, 5, and 6}
    E = {3, 4, 5, 6}
  2. P(E) =  
    n(E)
    n(S)
     
    (Since, P(E) is the probability of getting an event E, n(E) is the number of elements in the event E and n(S) is the number of elements in the sample space S )
    P(E) =  
    4
    6
     
  3. Hence, the probability that Brian will roll a number more than 2 is  
    4
    6
