1. A satellite camera makes it possible to observe over a square kilometer of ocean male blue whales jumping out of the water to capture the attention of females. Available data shows an average of 3 jumps/min. km2. A whale leaping out of the water will be considered here to be a relatively rare event, so you will apply the Poisson equation.

a) What is the mean, variance and standard deviation of the distribution of whale leaps?

b) Calculate the probability of seeing 2 or fewer whales leap for one minute over one km2.

2. Using the binomial equation, calculate the probability of getting two "ones" by rolling a pair of dice (casino players call snake eyes).

3. Calculate the probability of having only two coins falling on the tails side, when you flip 6 coins simultaneously
