What is the probability of getting all the heads in four throws of a coin?
| A. | 1/13 |
| B. | 12/16 |
| C. | 11/16 |
| D. | 1/16 |
|
Option: D Explanation : The chance of getting head in the first throw = 1/2 The chance of getting head in the second throw = 1/2 The chance of getting head in the third throw = 1/2 The chance of getting head in the fourth throw = 1/2 Thus the probability of getting heads in all the throws = (1/2) x (1/2) x (1/2) x (1/2) = 1/16 Hence the answer is (d).
