Paper 2Probability

A bag contains 55 red counters and 33 blue counters.

Three counters are drawn at random, without replacement.

Consider the following three probabilities:

PP the probability that all three counters are red

QQ the probability that exactly one counter is red

RR the probability that none of the counters is red

Place PP, QQ and RR in order of size, starting with the smallest.

AP<Q<RP<Q<R
BP<R<QP<R<Q
CQ<P<RQ<P<R
DQ<R<PQ<R<P
ER<P<QR<P<Q
FR<Q<PR<Q<P
