Brain likes to wear colored shirts. he has 10 shirts in the closet. three of these are blue, four are in different shades of red, and the rest are of mixed or different colors. what is the probability that he will wear a blue or red shirt?

The probability of wearing either a blue or red shirt is 7/10

Step-by-step explanation:

In order to get this, add together the total number of shirts that are those two colors.

3 blue + 4 red = 7 shirts

Now put that number over the total number of shirts.

7/10

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
