Two people, A and B, took part in the legal knowledge contest, with ten questions, six of which were selected and four were sentenced, each with one question.
The probability of a multiple-choice question and b true-false question is (6/ 10)*(4/9)=4/ 15.
If both A and B get the judgment questions, the probability is (4/10) * (3/10) = 3/25.
Then the probability that at least some of Party A and Party B get multiple-choice questions is 1-3/25=22/25.
