P(select a married couple) = P(person selected from Company A is one of the 50 with spouse at Company B) x P(person selected from Company B spouse of person already selected from Company A)
Now you can substitute the respective probabilities .

= 0,0025
If you're asking for the solutions to x and y, x is 10 and y is 8
Answer:
C-(7)
Step-by-step explanation:
Given figure is a trapezoid and 21 - x is the mid segment.
Therefore by mid-segment formula of a trapezoid, we have:
21 - x = 1/2(17 + 11)
21 - x = 1/2 * 28
21 - x = 14
21 - 14 = x
7 = x
x = 7
