4.(Swahili): It’s mid-afternoon. (Navajo)[correct answer]Now the probability of passing T1 has changed because you only have to guess correctly on one of thetwo remaining questions in the first section, a one-in-two chance.a)What is the new probability for T1?
b)Now what is the overall probability of passing the entire test?Answer:
d)And what is the probability of passing section T3, given that you have already passedsections T1 and T2?
e)The kicker: How do you explain the difference between 4c and 5c? Can you relate this to alarger context about conditional probability and making decisions?
Problem Hint:Compute the new probability for T1Derived the total probability using the new value of T1Use Bayes theorem with the updated values to compute new conditional probability ofpassing T3 given you have passed T1 and T2Consider conditional probability and how T1, T2 and T3 are considered a systems
