Question 440592
The only error is that you computed the probability of drawing a spade then a heart. However, you could also draw a heart then a spade. Hence, we would double the probability to 26/204 = 13/102.


The odds of drawing a spade and heart in some order is therefore (13/102)/(1 - 13/102) = (13/102)/(91/102) = 13:91.
