A bag contains 6 red marbles, 8 blue marbles, 5 green marbles and 1 yellow marble. Erin is going to pull marbles out of the bag, replacing the marble after each time. What is the probability that a red marble and then a green marble will be pulled out of the bag?

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
