Best ResponseYou've already chosen the best response.0that means either 3 heads and one tail or 4 heads the probability of all the possibilities can be seen by looking at the fourth row of pascal's triangle \[1,4,6,4,1\] the denominator of each of the probabilities is \(2^4=16\) so the probabilities are \[\frac{1}{16}, \frac{4}{16},\frac{6}{16},\frac{4}{16}, \frac{1}{16}\] for no heads, one head, two heads, three heads, four heads respectively
