Question

Of all the trees planted by a landscaping firm, 65% survive. What is the probability that 14 or more of the 16 trees they just planted will survive? (Use a table of binomial probabilities. Give your answer correct to four decimal places.)

Answer 1

P(X > 14) with p = 0.65 is same as P(X < 2) with p = 0.35

P(X < 2) = 0.0450
