Question

A two-day conference is going to be held in a city. The leading newspaper in the city says there is a 10% chance of rain on the first day of the conference and a 40% chance of rain on the second day.
If the newspaper’s figures are correct, the chance that it rains in the city during the conference is:


at least 0%, but we can’t get a better lower bound with the information given.
at least 10% but it might be less than 40%.
at least 40%.

Answer 1

If the newspaper’s figures are correct, the chance that it rains in the city during the conference is


at most 10%.
at most 40%.
at most 50%.
at most 100%; that’s the best upper bound we can get based on the information given.

Answer 2

Assuming the events 'rains on first day' and 'rains on second day' are independent, the probability of not raining on either day is given by
\[P(no\ rain\ either\ day)=(1-0.1)\times (1-0.4)=0.9\times 0.6=0.54\]
Therefore
\[P(rains\ during\ conference)=1-0.54=0.46\]

I am with a group of five of my friends. A box contains 8 pieces each of milk chocolate, white chocolate, and dark chocolate. The box is passed around the six of us, with each person taking 4 pieces. Assume that each person chooses at random without replacement from the available pieces. I am the last person to whom the box is passed. Find the chance that I pick 4 dark chocolates.
