This might be a simple question, but can anyone tell me how to solve it.
The probability of success of a particular type of experiment is 0.004. How many times the same experiment is to be repeated so that the probability of success becomes more than 0.7??
Is it simply, 0.004 * x = 0.7 and then find x which is 175
(0.996)^x * (0.004) implies where x = 731.
I did not understand how to approach this problem...
