Recall that ${p}_{n}(k)$ counts the number of partitions of k into exactly n positive parts (or, alternatively, into any number of parts the largest of which has size n).

My approach to this question: $\mathrm{\exists}x(P(x)\to R(x))$

I cannot verify if my answer is correct, any help to verify my answer would be appreciated and if I did wrong any help to explain why would also be appreciated.

Can someone help me to expand the below equation for $N=2$ and $N=3$?

${f}_{i}=\sum \{{e}_{i}:j\le i\le k\}$ for some $1\le j\le k\le N$.

Here ${e}_{i}$ is the unit vector of coordinate i in an N-dimensional space.

${R}_{1},{R}_{2},{R}_{3},{B}_{1},{B}_{2},{B}_{3},{Y}_{1},{Y}_{2},{Y}_{3}$

where R, B and Y denote red, blue and yellow, respectively. Find the probability that everyone gets a red card.

I have found that we have $3\cdot {6}^{5}$ odd numbers. I understand, that if number is divisible by 3, the sum of its digits also should be divisible by 3, but I don't know how to use this...

Prove the above relationship by using the Boolean definition. I tried $A+{A}^{\prime}B=A+B$, but end up with $A+B+{A}^{\prime}{B}^{\prime}(C+D)$, how can I go next?

Dealing with discrete Math is an interesting subject because discrete Math equations can be encountered basically anywhere from scheduling of sports games and live shows to education where each person is examined online. It is a reason why discrete math questions that we have collected for you are aimed at solutions that go beyond equations to provide you with the answers that will help you understand the concept. Still, discrete Math equations are explained as well by turning to problems in computer science, programming, software, and cryptography among other interesting subjects like software and mobile apps development.
