Quiz of the month – April

Test your knowledge and understanding of mathematics and logical thinking! Every month we have prepared a math or statistics quiz for you to test your knowledge or challenge your co-workers.

Has it ever happened to you that two of your classmates or colleagues at work had their birthday on the same day? You thought that was interesting and unlikely? Have you thought to find out what the probability of such an event is?

How many randomly selected people do you think you need for the probability, that two people in a given group will have the same birthday on the same day, to be at least 50%?
