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
Answer:
a)
b)
Step-by-step explanation:
In both parts of the problem y varies directly as x. So, they have the following form:
Where k is the constant of proportionality.
Therefore, you must find k and then write the equations.
a) Solve for k:
Then, the equation is:
b) Solve for k:
Then, the equation is:
