Answer:
Step-by-step explanation:
This problem lends itself to the binomial probability approach.
Focus on students who are not secretly robots.
Then P(student is not a robot) = 2/6, or 1/3. Here n=6 and x=2.
Then the desired probability is binompdf(6,1/3, 2), which, by calculator, comes out to 0.329.
Answer:
Third choice, m<EGB plus m<BGC!
Step-by-step explanation:
You know that m<BGC is 90 degrees. A straight line is 180 degrees. Line AGC is 180 degrees. Therefore, m<of EBG is 90 degrees. Hope this helps!
Part A: Yes, Triangle DEF and DBC are the same triangle, but DBC is smaller than DEF because it is just a cut off of DEF.
Part B: I am pretty sure it is angle C.
Part C: I am pretty sure it is angle D.
