People who think optimistically see the world as a place packed with endless opportunities, especially in difficult times. Avoid over-thinking and social comparison. 37 . If we’re somehow “better” than the person that we’re comparing ourselves to, it gives us an unhealthy sense of ...
Now we say there's a solution, if and only if there's a pospos that satisfies every index ii have been matched exactly aiai times. Now let's construct a solution to prove it. Assume that bpos,bpos+1,…,bnbpos,bpos+1,…,bn equals to 1,2,…,n−pos1,2,…,n−pos at the...

The number of the allowed zeros equals the number of all cases in the previous number. The number of allowed 1 equals the number of allowed zeros in the previous number so it equals the number of all cases in the number before the previous number. So the number of ways to construct zero...

5张牌中仅有2张号一样,样本空间大小仍为\dbinom{52}{5};事件集大小为13\times \dbinom{4}{2} \times \dbinom{12}{3} \times 4^3。因此抽出一对的概率为 \frac{13\times \dbinom{4}{2} \times \dbinom{12}{3} \times 4^3}{\dbinom{52}{5}} \times 100 \% = 42.3\% EX58 What is th...
