probability

Now, let’s say that you know just enough of these obscure languages to translate the first question in T1:

What time is it? (Klingon)

(Swahili): From dawn to setting sun. (Navajo)

(Swahili): Flowers grow around my house (Esperanto) so all of you may come in. (Klingon)

(Swahili): The sandwich will be eaten (Esperanto) because we are Klingons! (Klingon)

(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.

What is the new probability for T1?

Now what is the overall probability of passing the entire test?

And what is the probability of passing section T3, given that you have already passed sections T1 and T2?

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?
