In a certain university, students who have credit cards have either a Visa card or a Master card (or both). On selecting a student at random, the probability that she/he has a Visa card is 0.45, the probability she/he has a Master card is 0.3, and the probability that she/he has both a Visa card and a Master card is 0.2. Compute the following probabilities, writing only the final numeric result rounded to three decimal places. The probability that a randomly selected student has a Master card, given that she/he has a Visa card: The probability that a randomly selected student does not have a Master card, given that she/he has a Visa card: The probability that a randomly selected student has a Visa card, given that she/he has a Master card: The probability that a randomly selected student does not have a Visa card, given that she/he has a Master card: The probability that a randomly selected student has a Visa card, given that she/he has at least one card:
