3 math questions: 1) Probability question about Binomial distribution. I cannot remember exactly. It seems two situations, the possibility are the same. What's total number n? Remember Probability mass function of Binomial distribution will be very helpful. 2) Geometric progression， geometric sequence. Given first 3 numbers, find the 4th 3) a recurrence equation on a sequence of numbers F(n) = a*F(n-1)+b*F(n-2), both F(0) and F(1) are given, find F(100)

Why CGG and the role, Strength and Weakness, Maths questions. Presentation on a project you have worked on and a topic they sent to you beforehand.
Cannot remember well. First one is Unfair coin with probability of getting head less than 1/2, if we flip this coin 6 times the probability of getting 3 heads and 3 tails is 4/25. Second one is to solve Progression problems.
