Are the events "maried and "in the labor force" independent? Mutually exclusive?Explanation / Answer
75 % women participate in labor force
78% married , 61% married and participate in labor force
(a) P( women is married OR in labor force) = P( married) + P( labor force) - P( married and labor force)
= 0.78 + 0.75 - 0.61 = 0.92
(b) P( married OR labor force but NOT BOTH ) = P( married only ) + P( labor force only )
= ( 0.78-0.61) +(0.75 - 0.61)
= 0.78 + 0.75 - (2*0.61) = 0.31
(c) P( neither married nor labor force) = 1- P( either married or in labor force) = 1- 0.92 = 0.08
(d) P( married but not in labor force) = P( married) - P( both ) = 0.78 - 0.61 = 0.17
(e) Events married and labor force are not mutually exclusive because there are women which are both married and in labor force.
P(married) * P( labor) = 0.78*0.75 = 0.585
P( married and labor force) = 0.61
P( married ) * P( labor) IS NOT EQUAL TO P(married and labor)
Hence the events are DEPENDENT
