Two number cubes each have sides that are labeled 1 to 6 isis rolls the 2 number cubes what is the probability that the sum will equal to 4?
A number cube has sides labeled 1 to 6.
Hannah rolls the number cube 18 times.
How many times can she expect to roll a
number less than 3?
A2 C6
B3 D8

To find the probability that the sum of the two number cubes will equal 4, we first need to determine the total number of possible outcomes and the number of outcomes that satisfy the given condition.
The total number of possible outcomes can be calculated by multiplying the number of sides on each cube. In this case, each cube has 6 sides, so the total number of outcomes is 6 x 6 = 36.
Now, let's calculate the number of outcomes that result in a sum of 4. The following combinations of numbers on the two cubes will result in a sum of 4: (1, 3), (2, 2), and (3, 1). So, there are 3 favorable outcomes.
Finally, we can calculate the probability by dividing the number of favorable outcomes by the total number of outcomes: 3/36 = 1/12.
Therefore, the probability that the sum of the two number cubes will equal 4 is 1/12.
Two number cubes each have sides that are labeled 1 to 6. Iris rolls the 2 number cubes. What is the probability that the sum of the numbers rolled will equal 5?
I can get a 4 in these ways:
(1,3), (2,2), (3,1)
so what do you think?
