Answer:
The number of rolls = 36
Step-by-step explanation:
Thinking process:
A die has six sides (6).
Thus, the probability of striking a 6 is 
Let the number or sixes be 2
The number of roles for the die is given the following: 
where n is the number of sixes needed.
Therefore, the number of roles needed = 
A. W=2/12
4w=2/3
(Divide both sides of the equation by 4)
4w/4=2/3/4
(Any expression divided by it’s self is 1)
w=2/3/4
(To divide a fraction by a number, multiply by it’s reciprocal)
w=2/3 • 1/4
(Reduce the numbers with the greatest common factor 2)
w= 1/3 • 1/2
(Multiply the fractions)
w= 1/3 • 1/2= 1/6
1/6=2/12
