Q1: A and B are flipping a coin. A flips first, and then B. What is the probability of A winning first? Q2: What is the volume of a cube inscribed in a sphere with radius 1? Q3: There are 25 horses, each of which runs at a constant speed that is different from the other horses. Since the track only has 5 lanes, each race can have at most 5 horses. If you need to find the 3 fastest horses, what is the minimum number of races needed to identify them?

Soft skills description
basically math and brain teaser questions
1) 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. what is the probability of getting head for this coin. 2) Arithmetic serie: a,9,3a-b,3a+b .. find F(2020) . They key is that an arithmetic serie is defined by the difference between 2 consecutive terms is the same ( I didn't know/remembered, the interviewer reminded me of that)
