If the table below represents a probability model based on observed frequencies, what is the value of x ?Y C A R E SP(Y) 0.25 0.18 0.30 0.17 x
To find the value of x, we need to use the fact that the sum of all probabilities in a probability model must equal 1.
So, we add up the probabilities of each event:
0.25 + 0.18 + 0.30 + 0.17 + x = 1
0.90 + x = 1
x = 1 - 0.90
x = 0.10
Therefore, the value of x is 0.10.
wrong
My apologies for the mistake. To find the value of x, we can sum up all the probabilities and set it equal to 1:
0.25 + 0.18 + 0.30 + 0.17 + x = 1
0.90 + x = 1
x = 1 - 0.90
x = 0.10
Therefore, the correct value of x is 0.10.
