probability is super easy - don't overthink it or expect it to be harder...

P = 4/22 flute

P = 3/22 piano

P = 7/22 no instruments

P = 0/22 both

P=0 the answer is in the problem. If you're asked to simplify, then just reduce the fraction if it's reducible, so, for example flute could be reduced to 2/11, or changed to a percentage of 2 divided by 11, which is .18, or 18%
