3.9.5 At time 0, a blood culture starts with one red cell. At the end of 1 min, the red cell dies and is replaced by one of the following combinations with the probabilities as indicated: Two red cells One red, One white Two white Each red cell lives for 1 min and gives birth to offspring in the same way as the parent cell. Each white cell lives for 1 min and dies without reproducing.

Please do the following questions with full handwritten working out 

3.9.5 At time 0, a blood culture starts with one red cell. At the end of 1 min, the red cell dies and is replaced by one of the following combinations with the probabilities as indicated: Two red cells One red, One white Two white a leo 12 Each red cell lives for 1 min and gives birth to offspring in the same way as the parent cell. Each white cell lives for 1 min and dies without reproducing. Assume that individual cells behave independently. (a) At time n+min after the culture begins, what is the probability that no white cells have yet appeared? (b) What is the probability that the entire culture eventually dies out entirely?
