Answer 2

Answer:

(i) 25/35, (ii) 25/36

Step-by-step explanation:

A dice has 6 sides

Sample Space = 6

(i) Probability that 5 may not come once = 5/6

   Probability that 5 may not come again = 5/6*5/6 = 25/36

(ii) Probability that same number may not come once = 5/6

   Probability that same number may not come again = 5/6*5/6 = 25/36
