if 7 men and 5 womean have applied for job and 3 applicants are randomly selected from the probability that 2 are men​
barxatty [35]

The  probability that 2 men are selected is 49/144

Probability is the likelihood or chance that an event will occur.

If 7 men and 5 women have applied for job, the total number of people that applied will be 12 people

  • Pr(2 men are selected) = 7/12 * 7/12
  • Pr(2 men are selected) = 49/144

Hence the  probability that 2 men are selected is 49/144
