Found 2 solutions by ewatrrr, sunsetatdawn:Answer by ewatrrr(10682)   (Show Source): You can put this solution on YOUR website! ``` Hi Note: The probability of x successes in n trials is: P = nCx* where p and q are the probabilities of success and failure respectively. In this case p & q are = 1/2 or .5 nCx = P(exactly 6 heads in 10 coin tosses) = 210(.5)^6(.5)^4 = .2051 ```Answer by sunsetatdawn(4)   (Show Source): You can put this solution on YOUR website!If you are using a probability table to answer this, you have to calculate, n, x, and p. Where n is the number of trials, x is how many you want to get, and p is the probability of success. If looking for failure, you would need q with is 1-p, but as we aren't doing failure, will skip that for now. In this case, n=10 as we toss the coin 10 times. x = 6 as we want 6 heads, p = .5 as we have a .5 chance each trial to get a head. Then, using these you would use the table to find the probability of .205.
