Question

You are presented with a deck of 20 cards, numbered from 1 to 20 and can draw one card. If the number is odd, you win $22. If the number is even, you win nothing. If you play the game, what is the expected payoff?

Answer 1

$220

Explanation:

Because, from 1 to 20 there are 10 odd numbers (1, 3, 5, 7, 9, 11, 13, 15, 17, 19) so it is said that for one odd number you win $22, as for 10 odd numbers, that is $22 x 10 which is $220
