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.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
