A group of researchers is investigating jungles of Kashyyk in search of Wookies. There is a 35% probability that they will actually see a Wookie in the village among the giant wroshyr trees . However, the probability that they will see a Bantha during their expedition is fortyseven percent. 30% of the time the researchers will see neither a Wookie nor a Bantha. (HINT: Construct a probability matrix (Punnitt Square) and use it to solve for the probabilities. 
If a researcher is selected at random, what is the probability that the researcher saw a Wookie?
If a researcher is selected at random, what is the probability that the researcher saw a Bantha?
If a researcher is selected at random, what is the probability that the researcher saw neither a Wookie or a Bantha? 
If a researcher is selected at random, what is the probability that the researcher saw both a Wookie and Bantha?
