Answer:
The probability that both tests detect the bacteria is 83.66% ....
Step-by-step explanation:
First test has a probability of giving accurate results = 94% = 0.94
Second test has a probability of giving accurate results = 89% = 0.89
The probability that both tests detect the bacteria is:
Multiply both the probabilities:
=0.94*0.89
= 0.8366
Converting the value into percentage, we get
0.8366*100
= 83.66%
Thus the probability that both tests detect the bacteria is 83.66% ....
