Aand b are two events. the notation for conditional probability is p(b|a).
which notation is the probability of two events being not independent?

a. p(b|a) = p(a and b) / p(a)
b. p(b|a) = p(a) / p(b)
c. p(b|a) = p(b)
d. p(b|a) = p(b) / p(a)

a. P(B|A) = P(A and B)/P(A)

Step-by-step explanation:

The notation for conditional probability is P(B|A) and is defined as P(B|A) = P(A and B)/P(A) when the two events are not independent. When the events are independent we have that P(B|A) = P(B) which means that the occurence of B does not depent of the occurence of A. Another way of define independence of two events is to say that P(A and B) = P(A)P(B). Therefore, the answer is a. P(B|A)=P(A and B)/P(A)

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
