Puzzles

One activity that many of our members enjoy is puzzling! You can test yourself for fun with our brainteasers. Our quizzes and conundrums are updated regularly, so do check back on the page for the latest content, and if you get really good at them, why not find out what your IQ is by booking a Mensa Supervised IQ Test?

22/12/24 – Christmas Carols

A choir has learnt five carols for their Christmas Carol Service. One is Away in a Manger (AM), another is Silent Night (SN)

1) Using just five songs how many ways could the choir order the set?

2) If they played on two consecutive nights, what is the probability that they play AM before SN on both nights?

3) In how many of the possible arrangements would SN and AM be the first two carols sung (in either order)?
