Hello,Can you please help me with this probability question. I am practicing for my midterm coming in 2 weeks. I need a solution and explanations to this problem, please!I appreciate your help in advance ??

Problem 5: Pregnancy Tests Similar to most pregnancy tests, the pregnancy test from company ABC gives a false positive result (woman who is not pregnant tests positive) with probability 0.02 and a false negative rate (woman who is pregnant tests negative) with probability 0.02. Assume that 75% of all women who take a pregnancy test are actually pregnant. a) If a particular woman's test is positive, what is the probability that she really is pregnant? b) If the company ABC wants to improve the answer to part (a) more, should they focus on improving the false positive or false negative rate? Explain your answer with 2 or 3 sentences
