If the probability that a baby born in a certain hospital will speak in the next day is 1/4, what is the probability that at least 2 babies out of a cluster of 6 babies will speak tomorrow?

probability none will speak p0 = (3/4)6  

probability exactly one will speak p1 = 6*(1/4)*(3/4)5 

 

probability at least two will speak p2 = 1 - p1 - p0

 

You can crunch the numbers
