John flips 10 coins and lays them out in a straight line. a. how many possible combinations of heads and tails are possible? b. what is the probability of john flipping 10 tails (as a fraction).

For every coin, two options are possible. The formula for calculting all possibilities is where p is possibilities per time and t is times.

Therefore, there are which is 1024 combinations.

The formula for calculating probability is where w is the ways to achieve the desired outcome, and t is the total outcomes possible.

Therefore, there is a chance of flipping ten tails.

109 is the nearest whole number/final answer! : )
