You can put this solution on YOUR website! You buy 5 seeds with a guarantee that 80% of all seeds will bud. Assuming that the guarantee is indeed correct:
1. What is the probability no seed will grow into a plant?
Ans: 0.2^5 = 0.0032
2. What is the probability all seeds will grow into plants?
Ans: 0.8^5 = 0.328
3. What is the probability that exactly one seed grows into a plant?
Ans: 5*0.8*0.02^4 = binompdf(5,0.8,1) = 0.0064

Hi
Recommend Using stattrek.com to check Your results
until You are familiar with Using Your Calculator.
1) One could also Use A Casio fx-115 ES plus 0r fx-991 ES plus.
In a similar fashion..: Mode: DIST(binomial PD).
2) TI syntax for P(x-value) is binompdf(n, p, x-value).
P = .80, N = 5
1 p(X = 0) = binompdf(5,.80,0) = .0003 0R .03%
2 P(X = 5) = binompdf(5,.80,5) = .3277 0R 32.77%
3 P(X = 1) = binompdf(5,.8,1) = .0064 0R .64%
