if the type of below represents a probability model based on observed frequencies, what is the value of x equal when Y equals p(y) C equals 0.25 A 0.18 equals R 0.30 E equals 0.17 what does X equal?
To find the value of X when Y equals P(Y) and C equals 0.25, we need to use the formula for a probability model:
P(Y) = C * X + R * (1 - X) + E
Substitute the given values into the formula:
P(Y) = 0.25 * X + 0.30 * (1 - X) + 0.17
Since Y equals P(Y), we can set the equation equal to Y:
Y = 0.25 * X + 0.30 * (1 - X) + 0.17
Now we can solve for X by setting Y equal to P(Y):
P(Y) = 0.25 * X + 0.30 * (1 - X) + 0.17
We can then solve for X:
P(Y) = 0.25X + 0.30 - 0.30X + 0.17
P(Y) = 0.25X + 0.30 - 0.30X + 0.17
P(Y) = -0.05X + 0.47
From this equation, we can see that X cannot be determined without additional information such as the value of P(Y).
