Answer with explanation if possible

Suppose that the probability of germination of a beet seed is 0.9. If we plant 20 seeds and can assume that the germination of one seed is independent of another seed, what is the probability that 13 or fewer seeds germinate? 5'\"- 0.049905 3'\" 0.27017 -'\"'- 0.013509 -'\"' 0.391747 T'- 0.508253 Assume that arrivals of small aircrafts at an airport can be modeled by a Poisson process with rate 1 aircrafts per hour.
