Assume that there are 2 trials.

vampirchik [111]

Answer: The p(success) = 0.6

Your question is a little unclear, but I believe you are asking about the probability that at least one of the trials in the experiment were successful.

If that is the case, you simply have to add the probability of 1 success with the probability of 2 successes.

That is 0.48 + 0.16 = 0.64

Rounding our answer to one decimal place gives us 0.6.
