A ) 4571 B ) 4371 C ) 4271 D ) 4671
Steps to derive
1 Total number of families surveyed = 84 + 22 + 22 + 4 + 10 = 142
2 Number of families, whose favorite spot is Paris = 84
3 P(families whose favorite spot is Paris) = (number of families whose favorite spot is Paris) / (total number of families surveyed)
[Substitute and simplify.] 484142 = 4271
5 Experimental probability of a family, whose favorite vacation spot is Paris is 4271.
