The probability is
Explanation:
Let
Now let us consider the following:

probability of success from one toss be
#color(red)(p)# . 
probability of failure from one toss be
#color(red)(q)# . 
number of trials be
#color(red)(n)# . 
number of success be
#color(red)(r)# . 
number of failures is
#color(red)(nr)# .
Hence, the total probability of succeeding is represented by
Here,
Now, substituting this into (1), we get
