Answer:
3/10
Step-by-step explanation:
Total number of employees = 7 + 9 = 16
Probability of a man being chosen first to be promoted = 9/16
Probability of the second choice is still a man for promotion = 8/15
Why 8/15?
The number of men left who are eligible for promotion after the 1st man was chosen for promotion is 9 - 1 = 8
The total number of people left after the 1st person is chosen for promotion that are eligible for promotion is 16 - 1 = 15
Hence Probability of choosing 2 men for promotion = 9/16 x 8/15 = 3/10
20 = 2/5x + 8
20 - 8 = 2/5x
12 = 2/5x
12 × 5 = 2x
60 = 2x
60/2 = x
30 = x
x = 30
hope that helps, God bless!
