Answer:3
Step-by-step explanation:
So to start off on answering we are going to s<span>ubtract 3/5 from both of the sides:
</span><span><span><span><span><span>−1/</span>2</span>u</span>+<span>3/5</span></span>−3/5</span>=<span><span>1/6</span>−<span>3/<span>5
</span></span></span><span><span><span>−1/</span>2</span>u</span>=<span><span>−13/</span><span>30
Okay, so now we are going to mu</span></span><span>ltiply both sides by 2/(-1):
</span><span><span>(<span>2/<span>−1</span></span>)</span>*<span>(<span><span><span>−1/</span>2</span>u</span>)</span></span>=<span><span>(<span>2/<span>−1</span></span>)</span>*<span>(<span><span>−13/</span>30</span><span>)
</span></span></span>The final answer shall be:
u=<span>13/<span>15
I hope this helps! </span></span>
a. "Chocolate" and "Adults" (whatever those mean) will be independent as long as
"Chocolate" has the marginal distribution given by the second column, with a total probability of
. Similarly, "Adults" has the marginal distribution described by the third row, so that
. Then
Meanwhile, the joint probability of "Chocolate" and "Adults" is given by the cell in the corresponding row/column, with
.
The probabilities match, so these events are indeed independent.
Parts (b) and (c) are checked similarly.
b. Yes;
c. Yes;
