The probability that an at home pregnancy test will correctly identify a pregnancy is 0.97. Suppose 18 randomly selected pregnant women with typical hormone levels are each given the test. Rounding your answer to four decimal places, find the probability that all 18 tests will be positive at least one test will be negative

0.57795 and 0.4220

Explanation:

Given:

Probability of positive result = 0.97

Total number of women (observation) = 18

A. The Probability that all tests will be positive

Total probability of positive result is 0.57795

B. The Probability that one tests will be Negative.

= 1 - positive outcomes

= 1 - 0.57795

= 0.4220

Therefore Positive results is 0.5779 and negative result is 0.4220
