Answer:
When 5 winners are randomly selected, the probability that they are all men is 0.003.
Step-by-step explanation:
Among the contestants in a competition are 46 women and 23 men.
Total persons are =
When one winner is chosen, there are 68 people left, when second winner is chosen there are 67 people left and so on.
So, the probability that they are all men is given by:

=
= 0.002999 ≈ 0.003
Therefore, when 5 winners are randomly selected, the probability that they are all men is 0.003.

Answer:
substitution method
x = 7
y = 2
Step-by-step explanation:
2x - 2y = 10
x = 7
substitute for x:
2(7) - 2y = 10
14 - 2y = 10
subtract 14 from each side of the equation:
-2y = -4
divide both sides by -2:
y = 2
