It's known that if the sniper fires 3 times then the probability that from the three shots the sniper will strike at least one time and miss at least one time is 0.48.

A- Find "P".

So I was able to get these two equation according to Bernoulli's table:

$\displaystyle 3P*(1-P)^2 - 0.48 = 3P^2*(1-P)^1 - 0.48$

Are these correct ? according to the task ? can anyone check it and I'll solve it, and if It's not truth can anyone help me fix it ?

Final equation was :

$\displaystyle -6P^2 +3P=0 $

Final answer is : 0.8 / 0.2
