A. -10 > - 9 false
B. 1 > -18 true [ a positive is always > a negative ]
C. -25 > -30 true
D. 3 < -5 false
E. -10 < 3 [ a negative is always < a positive ]
BTW.....the easiest way to solve these is to plot both values on a number line.......the number to the left is always smaller than the number to the right
P(being a junior) = [75] / [ 75 + 60 ] = 75 / 135 = 5/9
P (preferring volyball) = [45] / [135] = 1 / 3
P(being a junior and preferring volleyball ) = 25 / 135 = 5 / 27
So, if independent
P( being a junior and preferring volleyball) = P( being a junior) x P( preferring volleyball)
5 /27 = 5/9 x 1/3 ???
5/27 = 5/27
So.....independent [answer D]
