Calculus will seem easy if you have the right tutor!

Let p = probability of passing a test. Then P(failed both) = (1 - p)

^{2}since the passing of either test is said to be the same.Solving the equation (1 - p)

^{2}= 0.1 gives p = about 0.68377but then it is alleged that the probability of passing both tests is 0.7 and that should be p

^{2}. Since p squared is 0.46754, you see that this data is contradictory.Therefore, I believe this problem to be faulty.
