Apen is dropped on a hardwood floor and a 1 is recorded if the pen crosses a line and a 0 if it does not. estimate the probability that the pen crosses a line in a single drop.

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

1. if events a and b are non-overlapping events, how do you find the probability that one or the other occurs? 2. what does it mean if p(a or b) equals 1?

Solve the equation: x - 9 = -6 + 5 a. 21 b. 7 c. 14 d. 2
