math question

2 shots at "1 in 8" =23.4% chance of 1 hit.
what chance of 1 hit does 1 shot at "1 in 6" and "1 in 10" have ?
Thought I had it figured out but sadly just confused myself more than usual.
Thanks to anyone who answers 

@beelee odds combinations are kinda counterintuitive.

Don't forget about the 1/60 chance of 2 hits!
