The probability is approximately

nothing.

(Round to three decimal places as needed.)

The data represent the results for a test for a certain disease. Assume one individual from the group is randomly selected. Find the probability of getting someone who tests negativenegative, given that he or she did not havedid not have the disease.			The individual actually had the disease
	YesYes	NoNo
PositivePositive	136136	66
NegativeNegative	2929	129129

There are 66+129 = 195 who don\'t have the disease.

Of those, 129 tested negative.

Thus,

P(negative|no disease) = 129/195 = 0.662 [ANSWER]
