    A very nice HR but very difficult questions.

    Several mental maths problems. Then probability questions. If you were wrong, she'll keep asking you what's your probability of getting it right? If I let you bet on your answer on $1/100/1000/1m how's your answer?

    • Two teams A and B played football twice. Two independent matches. The average shoot of A in match 1 is greater than B. The average shoot of A in match 2 is also greater than B. So can we say the average shoot of A is greater than B in two matches together? If so, why? If not, give me an example. -------- Failed to give the example, but I believe that the statement is not right.   2 Answers
