A local grocery store tested spinach samples for E coli bacteria using two different tests. The first test has a 94% probability

Afina-wow [57]

Answer: Probability that both tests detect the bacteria is 83.66%.

Step-by-step explanation:

Since we have given that

Probability of the first test giving accurate results = 84%

Probability of the second test is accurate = 89%

Probability of both tests detect the bacteria is given by

$\frac{94}{100}\times \frac{89}{100}\\\\=0.94\times 0.89\\\\=0.8366\\\\=83.66\%$

Hence, Probability that both tests detect the bacteria is 83.66%.
