If i have 47 sticks and 9 of the sticks are coloured red if i select a stick at random the chance of picking the a red stick is 19% (9 divided by 47 x 100). What i want to know is if i have two attempts to pick a red stick what is the percentage chance of me picking it?

I believe the 19% needs to be multiplied by 1.5 which would make it about a 28% chance. I'd like to know the correct way to work this out though because if the red stick isn't picked on the first attempt this means there are only 46 sticks left to choose from which would affect the result albeit only slightly so the multiply by 1.5 probably isn't the most accurate way of working it out.

Help much appreciated.
