Answer:

1/10 or 10%

Step-by-step explanation:

There are a total of five odd digits we can use (1,3,5,7,9). And we know the second to last digit is a four or a five. That means there is a total of 10 combinations (5 for each secondary digit). A guess would give you one of those ten combinations. Giving you a probability of 1/10 or 10%.

Prove that the sum of all natural numbers is -1/12.
ankoles [38]
This is not true. The infinite series


\displaystyle\sum_{n=1}^\infty n

converges if and only if the sequence of its partial sums converges. The k-th partial sum is

\displaystyle\sum_{n=1}^kn=\frac{k(k+1)}2

but clearly this diverges as k gets arbitrarily large.
