What is the probability of rolling a number less than 4 on a number cube labeled 1 through 6?
Leya [2.2K]
No matter the number of times you rolled the dice, the probability of getting a number is always 1/6. But here we can choose 4 numbers ( 1 to 4) hence the probability P( 1 or 2 or 3 or 4) = 4/6 2/3  = 0.6667 = 66.67% (A)
