if the probability of success is 0.07 what is the chance of succeeding 2/3 times?
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 * 0.931 = 0.013671
