Ajar contains 3 red, 4 blue, and 5 white marbles. Which of the following is the probability of drawing either a red or a
white marble?

2/3

Step-by-step explanation:

Total number of  marbles = 3 + 4 + 5 = 12

Pr (red marble) 3/12

Pr (Blue marble) = 4/12

Pr (white marble) = 5/12

Probability of drawing either a red or a white marble

= Pr ( red) + Pr (white)

= 3/12 + 5/12

= 8/12

= 2/3

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
