Asked by Bud
Researchers found that 30% of the larch trees in a certain geographical area had been damaged by fungi. (No fun, guy.) Consider a sample of 20 (independent) beach trees from the area.
(a) What is the probability that fewer than half are damaged by fungi?
(b) What is the probability that more than 14 are damaged?
(d) Find the 75th percentile for the number of damaged trees in groups of 20.
Used binomial distribution formula but I have no clue if it's even close.
