4 swahili its mid afternoon navajo correct answer now

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 the
two 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 passed
sections T1 and T2? e) The kicker: How do you explain the difference between 4c and 5c? Can you relate this to a
larger context about conditional probability and making decisions?
Problem Hint:
 Compute the new probability for T1
 Derived the total probability using the new value of T1
 Use Bayes theorem with the updated values to compute new conditional probability of
passing T3 given you have passed T1 and T2
 Consider conditional probability and how T1, T2 and T3 are considered a systems
