(probability) Getting a sum of either 5 or 9 on a roll of two dice

Mathematics
1 answer:
MAVERICK [17]3 years ago

Answer:

2/9

Step-by-step explanation:

From the image, the total number of outcomes when two die are rolled = 36

It can also be seen that a sum of 5 can be got 4 times and a sum of 9 can be got 4 times too

Therefore, the probability of getting a sum of 5 = 4/36

Probability of getting a sum of 9 = 4/36

The probability of getting either a sum of 5 or 9 gives;

4/36 + 4/36

= 2/9

Answer:

A

Step-by-step explanation:

The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is a^2 + b^2 = c^2 where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.

a = 6, b = 8, c= 10\\6^2 + 8^2 = 10^2\\36 + 64 = 100\\100 = 100

This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.

Step-by-step explanation:

If you think about it in a real life scenario, if one person does the job and then another person does the same job at the same speed wouldn't it be the same time? But if its not i think it would be 15 minutes because 45-30 = 15
