#18. Cards from an ordinary deck of 52 playing cards are turned face up one at a time. If the first card is an ace, or the second a deuce, or the third a three, or ..., or the thirteenth a king, or fourteenth an ace, and so on, we say that a match occurs. Note that we do not require that the (13n + 1)th card be any particular ace for a match to occur but only that it be an ace. Compute the expected number of matches that occur.© BrainMass Inc. brainmass.com February 24, 2021, 2:36 pm ad1c9bdddf
The probability of the first match of an ace is 4/52;
The probability of the second match of a deuce is 4/52;
The probability of the 13th match of a king is 4/52;
This shows how to co mpute teh expected number of matches occurring when drawing cards.
