A media personality argues that global temperatures are not rising, because every year an increase is reported, such as \( 0.09 \) degrees C. The difference from the previous year is less than the margin of error of about \( 0.13 \) degrees C, so that difference should be ignored. What is the best counterargument? 

(A) The margin of error is larger than the increase, so we should consider it an issue of just extra information and thus can be ignored. 

(B) The difference is only \( 0.04 \) , but that is still a significant change. 

(C) The change of \( 0.09 \) is not a lot and thus should be ignored. 

(D) The margin of error is quite small compared to the change year over year, so it is a significant issue. 

g. A ball is drawn from a box containing \(4\) red balls, \(7\) green balls and \(8\) blue balls. Find the probability that the ball drawn is 

i) red                     iii) blue 

ii) red or green      iv) not blue 

Determine whether events "drawing a red ball" and "drawing a blue ball" are mutually exclusive? 

If events \( A \) and \( B \) are disjoint, what is \( P ( A \cap B ) \) ? 

a \( 1 \) , because they share all outcomes. 

b \( 1 , \) because they do not share any incomes. 

c \( 0 , \) because they do nat share any outcomes. 

d \( 0 \) , because they share outcomes. 

What happens to the Addition Rule when the two events considered are disjoint? 

a If \( A \) and \( B \) are disjoint, then \( P ( A \cup B ) = P ( A ) + P ( B ) \)

b If \(A\) and \(B\) are disjoint, then \( P ( A \cap B ) = P ( A ) + P ( B ) \)

c If \(A\) and \(B\) are disjoint, then \( P ( A \cup B ) = P ( A ) - P ( B ) \) 

d If \( A \) and \( B \) are disjoint, then \( P ( A \cup B ) = P ( A ) + P ( B ) + P ( A \cap B ) \) 

Which of the following equations is used to find the mutually exclusive event? 

a \( P ( B ) - P ( A ) \) 

b \( P ( A ) + P ( A ) \) 

c \( P ( A ) - P ( B ) \) 

d \( P ( A ) + P ( B ) \) 

Geoff rode his bike along an \( 8 \)-mile path and lost his cell phone at some random location somewhere along the way. What is the probability that Geoff dropped his phone during the first mile or the last mile? 

a \( 25 \% \) 

b \( 28 \% \) 

c \( 12.5 \% \) 

d \( 22 \% \)
