4.Suppose a math class contains 26 students, 16 females (two of whom speak French) and 10 males (three of whom speak French). Compute the probability that a randomly selected student speaks French, given that the student is female.

5.A jar contains 7 red marbles numbered 1 to 7 and 5 blue marbles numbered 1 to 5. A marble is drawn at random from the jar. Find the probability that the marble is blue or odd-numbered.

Hint: P(blue or odd-numbered) = P(blue) + P(odd-numbered) - P(blue AND odd-numbered)
