2) sue, a botanist, is studying a new plant seed. if it is known that these seeds have a 95% probability of germinating. if sue plants 6 seeds, what is the probability that;
a) exactly four seeds will germinate?
b) at least five will germinated?
c) at most one will not germinated?
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
a) .95^4 * .05^2 = ?
B) "at least five" = 5 or 6
P(5) = .95^5 * .05 = ?
P(6) = .95^6
Either-or probabilities are found by adding the individual probabilities.
C) "at most one" = "at least five"
