Solution:
Total number of companies = 400
number of companies which offer free health fitness centers = 140
number of companies which does not offer free health fitness centers = 400 - 140 = 260
( a )
probability of randomly selecting company which offer free health fitness centers = p = 140 / 400 = 0.35
( b )
probability of randomly selecting company which does not offer free health fitness centers= q = 260/400 = 0.65
( c )
p + q = 0.35 + 0.65 = 1.00
Yes, these two probabilties add to 1.0
