Answer

The correct option is B False

On a standard die, all the face values (1, 2, 3, 4, 5, 6) are indeed less than 7. Thus, the number of favorable outcomes when trying to roll less than 7 is 6.

The probability ( P ) of rolling a number less than 7 is calculated as: $$ P = \frac{\text{number of favorable outcomes}}{\text{total number of outcomes}} = \frac{6}{6} = 1 $$

An event with probability 1 is termed a sure event. Therefore, rolling a number less than 7 with a die is definitely a sure event.
