Solve the problem.Suppose an experiment consists of tossing a coin seven times and recording the sequences of heads and tails.(a) How many outcomes are possible?(b) How many outcomes have exactly three heads?(c) How many outcomes have at least three heads?
What will be an ideal response?
| (a) | 27 = 128 |
(c) 128 - C(7, 0) - C(7, 1) - C(7, 2) = C(7, 3) + C(7, 4) + C(7, 5) + C(7, 6) + C(7, 7) = 99
