Two number cubes, each with the numbers 1 through 6, are rolled. What is the probability that the sum of the rolled numbers is 2?

Answers

Answer:

1/36

Step-by-step explanation:

The only way to get a sum of 2 with two dice is to roll 1s on both. there is one 1 on each dice, so you have a 1/6th chance for each. that gives you

1/6 × 1/6

which solves for your answer of

1/36

What is 6/12 divided by 3/4?

Answers

If you would like to know what is 6/12 divided by 3/4, you can calculate this using the following steps:

6/12 divided by 3/4
6/12 / 3/4 = 1/2 / 3/4 = 1/2 * 4/3 = 2/3

The correct result would be 2/3.
1st you have to take the common denominator which is 12. to turn the 3/4 into 12 you multiply by 3 because 4×3=12
what you do to the bottom you must do to the top so 3×3=9
you are left with 6/12÷9/12
flip and multiply so 6/12×12/9= 2/3

Will give 5 stars thx and brainliest 17 points plz hurry

Answers

All internal angles of a triangle will add up to 180 degrees.  Since angle A and B are given to us as 87 and 32 degrees respectively, we can easily find angle C by adding A and B together and then subtracting from 180.

87 + 32 = 119 degrees
180 -119 = 61 degrees

Angle C = 61 degrees

Now we can easily find angle 1 when we know that angles on one side of a straight line will always add up to 180 degrees.  Since angle C is 61 degrees then angle 1 is...

180 - 61 = 119 degrees
