The way I approached it was as follows: Starting from the initial state, one player has to win 2 points in a row to win. If that does not happen, we're back to the initial state. Therefore, P(A) = 0.49, P(B) = 0.09, P(repeating) = 1 - P(A) - P(B) = 0.42 I enjoy using the intuition that A is 49/9 more likely to win and then find the probabilities by dividing both by 0.42 (making 49 and 9 add up to 100 while preserving their proportions). Grats on the JS offer! Less

Shouldn't it be 0.7?

↳

84.5 % (sum of 0.49x(0.42)^n)

5/36

↳

5/36 is right.... Combinations that add up to six: 1 and 5, 2 and 4, 3 and 3, 4 and 2, 5 and 1. So we have 5 successes. There are 36 individual outcomes because there are 6 sides on each die and 6*6 = 36 So we have 5/36. Less

Hey, could you please tell me more about the final round interview at their office? Less

↳

Chance of 1 Heads = .5 Chance of 7 heads in a row = (.5)^7 to do this in your head think of fractions... (1/2)^7 = (1/2*1/2=1/4, * 1/2=1/8, * 1/2 = 1/16....if you do it seven times you get 1/128. so you have a better chance to pick out the penny with two heads (1/100) than to get 7 heads in a row (1/128) Less

↳

99 times out of 100 you take the normal penny. prob that normal penny give 7 heads in a row is 1/128. so, prob that he has special penny is 1/100 / (1/100 + 0.99*1/128) = 56.2% Less

↳

~56.4% that you have the 2-headed penny.

40 choclates in total.

43 chocolates

↳

30 chocolates for Rs. 30 then, 30/3 =10 Chocolates for 30 wrappers. Now, 10/3=3 Chocolates for that 10 Chocolate's wrapper (1 Remainder) now 3 Chocolate's wrapper+1 remainder=4/3=1 Chocolate (1 Remainder). 1w+1w=2 so there you won't get any chocolate after this. So total chocolates 30+10+3+1=44 Chocolates. Less

You’re making a profit. Selling at a higher price than what you bought

↳

The simple answer is that if you are short on a contango curve then you are losing money, for the curve is sloped positively. Less
