5. Darren has a bag containing red counters, yellow counters and green counters.
Altogether, there are 8 counters in the bag.
Darren chooses a counter from the bag at random.
On the probability scale below, R shows the probability that Darren chooses a red counter.
There is 1 yellow counter in the bag.
(a) On the probability scale, mark with a Y the probability that Darren chooses a yellow counter. [1]
(b) On the probability scale, mark with a G the probability that Darren chooses a green counter. [1]
