I need to write both of these in R

12 Carry out a computer simulation of the situation in Exercise 10, but with this difference: at the splitting times (t=1,2,) there is only a 0.75 chance of the splitting occurring and a 0.25 chance that it does not occur. If no split occurs, then the next opportunity for that bacterium to split is 1 hour later. Tabulate the population for t=1,2,3,,15 and see whether this tabulation can be fit with a function of the form P(t)=P(0)rt. 16 Write a computer simulation to determine the waiting time till conception of a couple with p=0.2. [Use a random-number generator to pick a number in the interval (0,1). If the number drawn is in (0,0.2), this signifies conception.] Now repeat the simulation for this couple 100 times and compute the average waiting time over all trials. Compare the result with the theoretical value obtained from w=1/p
