In: Statistics and Probability
it is found that the probability a certain plant flowers in its
first year is 40%. A gardener purchases 1000 of these first-year
plants. What is the variance and standard deviation of the random
variable X which is the number of plants that flower in the first
year?
This question can be solved using binomial distribution law of probability. We have formula for variance and standard deviation . This question has been solved in detail below.
