Question

The probability is 0.6 that an "unfair" coin will turn up tails on any given toss. if the coin is tossed 3 times, what is the probability that at least one of the tosses will turn up tails?

Answer 1

The probability of getting zero tails in three tosses is given by:

`(0.4)^(3)=0.064`
Therefore the probability that at least one of the tosses will turn up tails is:
1 - 0.064 = 0.936
The answer is 0.936
