. Let X denote the wing length in millimeters of a male gallinule and Y the wing length in millimeters of a female gallinule. Assume that X is N(184.09, 39.37) and Y is N(171.93, 50.88) and that X and Y are independent. If a male and a female gallinule are captured, what is the probability that X is greater than Y

The probability that X is greater than Y is 0.5754.
Step-by-step explanation:
It is provided that,
It is also provided that X and Y are independent.
We need to compute the value of:
P (X > Y) = P (X - Y > 0)
Compute the mean and standard deviation of (X - Y) as follows:
Compute the the value of P (X > Y) as follows:
Thus, the probability that X is greater than Y is 0.5754.

Explanation:
If you plug in 6(2+40)= 252
Using PEMDAS, solve in the parentheses first! which will be 42.
6(42)=252
6 x 42 = 252
making x=2 because plugging in x makes this equation true
252= 252
