Answer:yes it is because it is a number with radical
Step-by-step explanation:
Answer: P (atleast one is careful) is
1 - 0.012 =0.988
B) It is very possible that the result is not valid because the sample may not be representative of the people who use public Wi-Fi
Step-by-step explanation:
P(not careful) =1 - 0.67 = 0.33
P (4 all not careful) = (0.33)^4 =0.012
P (atleast one is careful) = 1 - 0.012 =0.988
Answer: The first experiment has M probabilities, and the second has I(m) outcomes, that depends on the result of the first.
And lets call m to the result of the first experiment.
If the outcome of the first experiment is 1, then the second experiment has 1 possible outcome.
If the outcome of the first experiment is 2, then the second experiment has 2 possibles outcomes.
If the outcome of the first experiment is M, then the second experiment has M possibles outcomes.
And so on.
So the total number of combinations C is the sum of all the cases, where we exami
1 outcome for m = 1

2 outcomes for m=2

M outcomes for m = M
C = 1 + 2 + 3 + 4 +...´+M
