On February 28, 2013, a Field Poll Survey reported that $61 \%$ of California registered voters approved of allowing two people of the same gender to marry and have regular marriage laws apply to them. Among 18 to 39-year-olds (California registered voters), the approval rating was $78 \%$. Six in ten California registered voters said that the upcoming Supreme Court's ruling about the constitutionality of California's Proposition 8 was either very or somewhat important to them. Out of those CA registered voters who support same-sex marriage, $75 \%$ say the ruling is important to them.

In this problem, let's:

• $C=$ California registered voters who support same-sex marriage.

• $B$ = California registered voters who say the Supreme Court's ruling about the constitutionality of California's Proposition 8 is very or somewhat important to them

• $A=$ California registered voters who are 18 to 39 years old.

Are $C$ and $B$ mutually exclusive events? Show why or why not.

Walgreen Co. , the largest drug store chain in the United States, reported inventories of $7,213 million and$6,852 million in its February 28, 2014, and August 31, 2013, balance sheets, respectively. Cost of goods sold for the six months ended February 28, 2014, was $27,132 million. The company uses primarily the LIFO inventory method. A disclosure note reported that if FIFO had been used instead of LIFO, inventory would have been higher by$2,200 million and $2,100 million at the end of the February 28, 2014, and August 31, 2013, periods, respectively. Calculate cost of goods sold for the six months ended February 28, 2014, assuming Walgreen used FIFO instead of LIFO.

The graph shown is based on more than 170,000 interviews done by Gallup that took place from January through December 2012. The sample consists of employed Americans 18 years of age or older. The Emotional Health Index Scores are the sample space. We randomly sample one Emotional Health Index Score.
