A lake contains two kinds of trout, rainbow and brown.

2. A lake contains two kinds of trout, rainbow and brown. 


It is estimated that 40% of the trout are rainbow. 


Of the rainbow trout, 60% are mature, and of the brown trout, 30% are mature. 

You have a trout on the line and see that it is a keeper (mature). 

What is the probability that it is a rainbow?
