The sum of all cars will be = 70 + 30 + 50 + 80 + 20 = 250 So, <span>the probability that’s the nexts car to drive by will be red = (red cars)/(total cars) = 50 / 250 = 0.2 </span> the probability that’s the nexts car to drive by will be <span>blue = (</span><span>blue cars)/(total cars) = 70 / 250 = 0.28 then </span> <span>the probability that’s the nexts car to drive by will be red or blue = 0.2 + 0.28 = 0.48 </span>
If you create the graph and then plot the points you will get a depiction of the trapazoids. using this you will find that they have reflected over the x=3 line.
