Question

3.7. Consider the performance function Y- 3X1-2X2 where X1 and X2 are both normally distributed random variables with Rx.-16.6 Ох.-2.45 μΧ.-18.8 ơXs: 2.83 The two variables are correlated, and the covariance is equal to 2.0. Determine the probability of failure if failure is defined as the state when Y0.

3.7. Consider the performance function
Y = 3X, - 2X2
where X, and X2 are both normally distributed random variables with
ux, = 16.6
4Xq = 18.8
ох, 2.83
Ох, 2.45
The two variables are correlated, and the covariance is equal to 2.0. Determine the
probability of failure if failure is defined as the state when Y < 0.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
