Answer:

The correct option is D.

Step-by-step explanation:

Two events are known as independent events if the probability of one event does not affect the probability of second event.

If A and B are two independent event, then

P(A\cap B)=P(A)\cdot P(B)                 .... (1)

The formula of conditional probability is

P(B|A)=\frac{P(A\cap B)}{P(A)}

If A and B are two independent event, then by using equation (1) we get

P(B|A)=\frac{P(A)\cdot P(B)}{P(A)}

P(B|A)=P(B)

Therefore the correct option is D.

Step-by-step explanation:

Given:

\left\begin{array}{ccccc}{Play}&{1}&{2}&{3}&{4}&{Yards}&{+4}&{-6}&{-2}&{+3}\end{array}\right

Required [Missing from the question]:

Determine the play with the least change in yard?

To do this, we ignore the sign in front of each yard before we analyze.

So, we have:

Play 1 has a change of 4

Play 2 has 6

Play 3 has 2

Play 4 has 3

<em>From the above analysis, play has the least (which is 2)</em>
