Let T be used to model the number of days, t , an insect survives after hatching. The probability that the insect survives more than t days is 225 (t +15) , t 0

a)Find the c.d.f

b)find the mode and median

c)find the probability that a randomly selected insect will die 3 days after hatching

d)Given that an insect survives 3 days,what is the probability that it will survive for at least 5 more days
