    A bag of 27 tulip bulbs contains 11 red tulip​ bulbs, 9 yellow tulip​ bulbs, and 7 purple tulip bulbs. Suppose two tulip bulbs are randomly selected without replacement from the bag. ​(a) What is the probability that the two randomly selected tulip bulbs are both​ red? ​(b) What is the probability that the first bulb selected is red and the second​ yellow? ​(c) What is the probability that the first bulb selected is yellow and the second​ red? ​(d) What is the probability that one bulb is red and the other​ yellow?

    Answer:

    (a) 55/351

    (b) 11/78

    (c) 11/78

    (d)529/702

    Step-by-step explanation:

    Total number of tulips = 27

    Red tulip​ bulbs = 11

    Yellow tulip​ bulbs = 9

    Purple tulip bulbs = 7

    Note that this probability is without replacement

    (a) What is the probability that the two randomly selected tulip bulbs are both red?

    Probability (that both are red)

    = 11/27 × 10/26

    = 55/351

    (b) What is the probability that the first bulb selected is red and the second yellow?

    Probability (that the first is red and the second is yellow)

    = 11/27 × 9/26

    = 99/702

    = 11/78

    (c) What is the probability that the first bulb selected is yellow and the second red?

    Probability (that the first bulb selected is yellow and the second red)

    9/27 × 11/26

    = 99/702

    = 11/78

    (d) What is the probability that one bulb is red and the other yellow?

    = Probability( that one bulb is red and the other yellow)

    = 11/27 + 9/26

    = (26 × 11) +(27 × 9)/702

    = 529/702
