Jevan must paint 3 rooms in a house. Room A can be painted orange, red or green. Room B can be painted orange, white or red. Room C can be painted white, red or green. The 3 rooms cannot all be painted the same color. In how many different ways could Jevan paint the 3 rooms?
1) 24
2) 26
3) 27
4) 63
5) 64

2) 26

Step-by-step explanation:

The first thing to paint is to divide it into three parts, like this:

1st part:

Room A can be painted orange, red or green.

Therefore, we have 3 ways to do it.

2nd part:

Room B can be painted orange, white or red.

Therefore, we have 3 ways to do it.

3rd part:

Room C can be painted white, red or green.

Therefore, we have 3 ways to do it.

To know the total number, each part must be multiplied, that is:

3 * 3 * 3 = 27

However, some of these 27 possible results break the condition that the 3 rooms cannot be painted the same color, that only happens when the three rooms are painted red.

Therefore, the number of times would be:

27 - 1 = 26

step-by-step explanation:

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
