1. A fish researcher has 8 Mangrove Rivulus fish from 3 lineages that vary in terms of their tolerance of salinity: 2 fish only tolerate low salinity, 3 fish only tolerate high salinity, and 3 fish have no salinity requirement. Four fish are selected at random without replacement. If X is the number that tolerate low salinity and Y is the number that tolerate high salinity, find:
2. the probability that one fish is selected with low salinity, and one fish is selected with high salinity tolerance, i.e., P(X = 1, Y = 1)
3. the probability that only fish that have no salinity preference are selected, i.e., P(X=0,Y=0)
4. fish that tolerate high salinity (Y) and its meaning (here I keep getting a percentage that is over 1 ~1.26)
