well great (sarcasm) in two ways, calculator gave me 0.0465... not 0.024, although this brings the question, since i am drawing them all from the same deck, wouldn't the chance change with each card drawn? compared to drawing each card from a different deck? and r would have to be 4?
and i think i know what i did wrong, but am unsure, p should be 1/4 'th right? 1 out of 4 chance to draw a heart?
