Your math is off. You have a 20% chance of hitting a club on the turn, You can't add the fractions, otherwise you would have a 100% chance of hitting a club for every 5 cards (1/5+1/5+1/5+1/5+1/5) which is obviously not true.

You actually have a 36% chance of hitting a club on the next two cards.
Chance of hitting a club on the turn, missing the river: (1/5)(4/5)=.16
Chance of missing the turn, hitting the river1/5)(4/5)=.16
Chance of hitting on turn and river1/5)(1/5)=.04

Total:36% chance of making a flush
note 2/5 (0.4) approx equal to .36. I know I lost the (n-1)/n part but when playing poker I approximate to free up brain space. I think 10% error acceptable on the fly.
