A jar has one red, one orange, one yellow, one green, one blue, and one purple marble in it. Wha probability of selecting a purple marble?

the probability would be

1 in 6, 1/6, or 1:6

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
