The probability that a marble is green is 0.21, the probability that it is big is 0.58, and the probability that it is green or big is 0.61.
What is the probability that a randomly chosen marble is green and big?

How am I supposed to solve this??? Do I add them all together o

yes because they have the same amount of green and blur marbles.

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."

d.) yes, because the volume of the cone is greater than the volume of the sphere
