if the probability of success is 0.07 what is the chance of succeeding 2 out of 3 times

P(success)=0.07

P(failure)=1-0.07 = 0.93

You could get SSF, SFS, FSS

So there are 3 different ways you can succeed 2 out of three times

Each of these will have a probability of 0.07*0.07*0.93

so the probability of 2 successes 3*0.07*0.07*0.93 = 0.013671

Another way to do this is;

3C2 * 0.072 * 0.93= 0.013671
