A certain type of tomato seed germinates 90% of the time. A novice gardener has planted 25 seeds.

Q14) The probability that 21 seeds will germinate is :

less than 0.1% between 0.1% and 1 between 1% and 10 between 10% and 15%.

Q15) The probability that fewer than 23 seeds will germinate is :

less than 40% between 40% and 45 between 45% and 50 50% or more

Q16) The expected number of seeds that will not germinate is

23 or more 22,5 2,5 2,25

Q17) Satisfied with his first results, our gardener decides to plant 200 seeds. He would like to know the probability that more than 180 seeds will germinate among the 200 seeds planted. Can the Poisson distribution be used to estimate this probability?

- No, np is greater than 5

- Yes, n is greater than 20

- No, n is not large enough

- There is not enough information to answer
