Maritza rolls two number cubes that are numbered 1 through 6. What is the probability that the total on both cubes will be a prime number?

50% Chance

1/2

Step-by-step explanation: 2,3, and 5 are the prime numbers 1-6. That means 3/6 of those numbers are prime. 3/6 simplifies to 1/2 or 50%

5/12 or 41.66666% or 42%

Step-by-step explanation:

There are two number cubes both listed as 1-6. In order to find the probability of the total on both cubes being a prime number, you'd have to first come up with the prime numbers possible by addition. You should get 2, 3, 5, 7, and 11.

After finding the numbers possible, you have to find each of the different number combinations that you could use to get there. You should get 15 different possibilities.

2:

1, 1

3:

1, 2

2, 1

5:

1, 4

4, 1

2, 3

3, 2

7:

1, 6

6, 1

2, 5

5, 2

3, 4

4, 3

11:

5, 6

6, 5

Now, you have to find the total possibilities. You should get 36.

1, 1

1, 2

1, 3

1, 4

1, 5

1, 6

2, 1

2, 2

2, 3

2, 4

2, 5

2, 6

3, 1

3, 2

3, 3

3, 4

3, 5

3, 6

4, 1

4, 2

4, 3

4, 4

4, 5

4, 6

5, 1

5, 2

5, 3

5, 4

5, 5

5, 6

6, 1

6, 2

6, 3

6, 4

6, 5

6, 6

Now all you have to do is divide the two numbers (15 and 36), and you should get 5/12 as an exact answer, or 41.66666 (repeating) %, which you can round up to 42%.

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
