Let M be the event that a randomly selected IRSC student is male and P(M) = 0.47. Round solutions to three decimal places, if necessary. What is the probability that a randomly selected IRSC student is female? P(F) 0.53 Suppose two IRSC students are selected at random and calculate the following probabilities. P(Both students are male) 0,221 X P(Both students are female) 0.281 P( the first student is male and the second student is female) 0.249 Hint
