Given P(X) = 0.5, P(Y) = 0.4, and P(Y|X) = 0.3, what are P(X and Y) and P(X or Y)?

scZoUnD [109]

Use the definition of conditional probability to find the "and" probability:

$P(Y\mid X)=\dfrac{P(X\cap Y)}{P(X)}\implies P(X\cap Y)=0.3\times0.5=0.15$

Use the inclusion/exclusion principle to find the "or" probability:

$P(X\cup Y)=P(X)+P(Y)-P(X\cap Y)=0.5+0.4-0.15=0.75$

The slope is -1 meaning down 1 over 1
y intercept is 10 (0, 10)
when x is 1 y is 11 (1, 9)
when x is -1 y is 9 ( -1, 11)
