Suppose there are n lily pads located on a unit circle, and a frog initially is sitting on one of them at time = 0. Every minute this frog will make a jump to the lily pad that is next to it, either to the left or to the right with probability = 1/2. Find the expected time in minutes for this frog to visit every lily pad on the unit circle.
You flip a weighted coin that comes up Heads 40% of the time and Tails 60%. If you flip this coin 5 times, what is the probability that you see at least 3 Tails, rounded to the nearest percent?
