67.81%

Answer 1

There is numerous information already given in the question. Based on that information, the answer can be easily deduced. Let us now focus on the problem in hand.Probability that both experiments become successful = 22%Probability of the second experiment becoming successful = 31%Probability that the first experiment becoming successful = 22/31                                                             = 0.7096Percentage that the first experiment will become successful = 0.7096/100                                                         = 70.97%
