Answer:
All of the following are rational except 3.14159...
Step-by-step explanation:
Remember that, for independent events, the probability that both occurr is the product of the individual probabilities.
a) Probability of being contacted: 78% = 0.78
Probaility of refusing: 1 - 22% = 1 -0.22 = 0.78
Combined probability: 0.78*0.78 = 0.6084
b) The probability of failing to contact or making contact and not geeting them to agree 1 - the probability of contacting and getting them to agree.
The probabilityof contacting and getting them to agree is 0.78*0.22 = 0.1716
The the answer to this question is 1 - 0.1716 = 0.8284
You didn't tell us what the choices are, so there's
nothing to pick from.
The most accurate estimation of (54 - 16) is 38 .
The answer could be
-1287
