The data represent the results for a test for a certain disease. Assume one individual from the group is randomly selected. Find
1 answer:
Answer:
0.9295 = 92.95% probability of getting someone who tests negative, given that he or she did not have the disease.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
11 + 145 = 156 people did not have the disease.
Out of those, 145 tested positive. So
0.9295 = 92.95% probability of getting someone who tests negative, given that he or she did not have the disease.

Answer:
Step-by-step explanation:
When we throw a die , Total outcomes =6
When we throw 3 dice , Total outcomes = 6 x 6 x 6 = 216 [by fundamental counting principle]
Given : Three fair dice are rolled, one red, one green and one blue.
Favorable outcomes : When the upturned faces of the three dice are all of different numbers i.e. no repetition of numbers allowed
By Permutations , the number of favorable outcomes =
The probability that the upturned faces of the three dice are all of different numbers =
The probability that the upturned faces of the three dice are all of different numbers is .
