<PRE><B>Question 1114112</B>
Tossing 4 coins and recording the number of heads uses a binomial probability distribution
:
the answer jpg just shows me a white page with a dark band at the top
:
in general, if you want to know the probability of a certain number of heads for a toss you use the binomial probability formula
:
Probability (k successes in n trials) = nCk * p^k * (1-p)^(n-k), where nCk = n!/(k! * (n-k)!)
:
for this problem k=number of heads, p=0.5 and n=4
