Answer:

  • 7/50, none of the answer choices

Step-by-step explanation:

  • Total number = 26
  • Number of boys = 14
  • Number of girls = 12

There are three ways of choosing 2 boys and a girl:

  • P(bbg) = 14/26*13/25*12/24 = 7/50
  • P(bgb) = 14/26*12/25*13/24 = 7/50
  • P(gbb) = 12/26*14/25*13/24 = 7/50

As we see the answer is 7/50 and all the answer choices are different from this
