Drawing a least one king when you draw a card from a standard deck 8 times (replacing the card each time you draw, so there are always 52 cards in the deck)

P(at least one king in 8 attempts)= [P(1 king + 2 kings + 3 kings + 4 kings]^8 =
1/52 + 2/52 + 3/52 + 4/52 = 10/52^8

Not sure how to solve, should I subtract 1 from the answer.

  1. prob(a king) = 4/52 = 1/13
    prob(not a king) = 12/13

    let's find the prob of NOT getting a king, 8 times in a row
    = (12/13)^8
    but we DON'T want that to happen

    so prob of at least one king somewhere
    = 1 - (12/13)^8
    = appr .4729

    btw, your attempt makes no sense to me
