In a cup of 16 pens, 3 are green, 9 are blue, 1 is black, and the rest are red. if a pan is selected at random, what is the probability that it is green or red? A. 5/8
B. 1/4
C. 3/8
D. 3/4​

3/8

Step-by-step explanation:

If you add the values 3 green pens plus 3 red pens you get 6 which makes the fraction 6/16 then you simplify and get 3/8

3/8

Step-by-step explanation:

16-1-9 = 6

6/16 = 3/8

the area will increase 6073.51 ft

the circumference will increase 69.08 ft

Step-by-step explanation:

(22.5 * 3.14)^2=4991.4225 ft^2

67/2=33.5

(33.5*3.14)^2=11064.9361 ft^2

2(3.14*22.5)=141.3 ft

67/2=33.5

2(3.14*33.5)=210.38 ft
