The most straight forward way to do this would be to use the BinomialDistribution function in the Statistics`DiscreteDistributions` package. As follows:

<<Statistics`
Random[BinomialDistribution[100,0.6]]

which returns the number of heads that might occur with 100 tosses of a coin with a 0.6 probability of heads.

Or if you didn't want to use the add on packages

Count[#>0.4&/@Table[Random[],{100}], True]

will accomplish the same thing
