Answer:
Step-by-step explanation:
Population of X is {1, 1, 2, 2, 2, 3, 3, 3}
Based on that, X's expected value, variance and standard deviation can be calculated as follows:
Expected Value, μ = 2.125 or 2.13
Variance, σ2 = 0.609375 0r 0.61
Standard Deviation, σ = 0.78062475 or 0.78
Y is same as the missing angle, the triangle need to equal to 180 so if you add 20 to 60 it equal to 80
use 180 to subtract to 80 you will get the missing x, x=80
