suppose that 8 cards are drawn from a well shuffled deck of 52 cards what is the probability that all 8 are spades

1287 / 752538150 ≈ 0.00017%

Step-by-step explanation:

Of the 52 cards, 13 are spades.

There are ₁₃C₈ ways to choose 8 spades from 13.

There are ₅₂C₈ ways to choose 8 cards from 52.

So the probability is:

₁₃C₈ / ₅₂C₈

= 1287 / 752538150

≈ 0.00017%

your answer would be 10x - 1

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
