Question

A coin is tossed nine times what is the probability of getting all tails express your answer as a simplified fraction or decimal rounded to four decimal places

Answer 1

The probability of getting a tail on each toss is:

`(1)/(2)`

Since there is only one way of getting all tails, it follows that the required probability is given by:

`((1)/(2))^9\approx0.0020`

Hence, the required probability is approximately 0.0020
