Detailed explanation-1: -probability of occurrence of this event is zero. We know that, A die only has dots or numbers from 1 to 6, i.e., 1, 2, 3, 4, 5, 6. ∴ The probability of getting number 7 = 0.
Detailed explanation-2: -Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
Detailed explanation-3: -Possible outcomes on a single roll of a die are 1, 2, 3, 4, 5 and 6. Therefore, the chance of getting a 7 (favourable outcome) on rolling the die once is 0. Thus, the probability of the event is 0 or it is an impossible event.
Detailed explanation-4: -Therefore the probability of getting the number 7 is zero.
Detailed explanation-5: -The probability of rolling a 7 on a single die = = 0/6 = 0. Hence, the probability of rolling a 7 on a single die is 0.
