Suppose you roll two number cubes and find the probability distribution for the sum of the numbers. which two sums have the same probability distribution and would be represented with equal bars on a bar graph?

When you roll a number cube, there is a possibility of a number from 1 to 6 appearing. i.e. 1, 2, 3, 4, 5, or 6 can appear.

The same goes for the second number cube.

The table below presents the possible outcomes of rolling two number cubes with the sum written as exponent.

From the table it can be seen that the sums: 2 and 12 appeared only once and hence will represent the shortest bars if the distribution is represented in a bar chart.

Therefore, the two sums that are represented by the shortest bars on a bar graph of this distribution are 2 and 12.

Hi Constance8789,

A dice is able to have the probability that it can roll and one to six but when you add a secnd dice you can roll up to 12. 2 and 12 wil represent equal bars on a graph compared to the other numbers.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

40% off the regular price is the correct answer.
