Answer:
18 times
Step-by-step explanation:
Sample space ; roll of 2 number cubes = 6^2 = 36
Sum of 4 in 2 cube rolls = 3
Probability = required outcome / Total possible outcomes
P(sum of 4) = 3 / 36 = 1 / 12
If number cube is rolled 216 times :
Probability on 1 roll * Number of rolls
(1 / 12) * 216
0.0833333 * 216
= 18
Equals 1 over 7 because 63/9 is 7. The answer is 1/7
in simplest form is
.
Because:
Divide the numerator (2) and denominator (50) by 2. Hope this helps!
