You have set every thing up correctly.
Now it is just basic algebra.
Do the algebra.
I have been trying desperately to solve this task, unfortunately I had no success whatsoever.
Here is the task:
"In a certain experience the probability of success is"P" (0<P<1).
It's known that if all four tests are executed then the probability of all of them to succeed is multiply 16 from the probability that all four experiences will fail. A: Find P."
final result is : 2\3
So I was able to calculate according to Bernoulli's table and get this equation ;
Can any one please help me solving this whole task please?
