The odds that a computer engineering student on a field trip to Al- gonquin parc, encountering a snake for one day are estimated at 13%. We assumes that such an event is independent from one day to the next. 1. What is the probability that the third snake will not be encountered by this student on the fifth day of the field trip? 2. It is assumed that two days have passed without such an encounter having location. What is the probability that this student will wait at most three days to meet a first snake there?
