Question

A drawer contains 5 white shirts, 3 yellow shirts, and 4 black shirts. a shirt is randomly selected from the drawer and set aside. then another shirt is randomly selected from the drawer. what is the probability that the first shirt is yellow and the second shirt is black?

Answer 1

`|\Omega|=12\cdot11=132\\|A|=3\cdot4=12\\\\P(A)=(12)/(132)=(1)/(11)\approx9.1\%`
