We will continue with a few numerical puzzles. Please give your best guess to each of the questions.

 

Out of 1,000 people in a small town, 500 are members of a choir. Out of these 500 members in a choir, 100 are men. Out of the 500 inhabitants that are not in a choir, 300 are men.

 

What is the probability that a randomly drawn man is a member of the choir?

Please indicate the probability in percent. This means that you should not use any commas or dots.

Imagine we are throwing a loaded die (6 sides).



The probability that the die shows a 6 is twice as high as the probability of each of the other numbers.

 

On average, out of these 70 throws how many times would the die show the number 6?
