In a particular African coastal region, seismologists studied tsunamis by observing seismic shifts and earthquakes in the South Pacific Ocean. During their study, they were able to note the number of earthquakes as well as the number of resulting tsunamis in this region. They observed earthquakes and found that there was a probability of a tsunami hitting the region in the next year based on previous data. What is the probability that the region will have tsunamis in the next year?

A statistics class has ten homework assignments. The first two assignments take 2 hours each to complete. The next three assignments take 4 hours each to complete. The three after that take 10 hours each, and the final two assignments take 15 hours each. On average, how long does it take to complete a homework assignment?
