    thanks! I haven't been taught this in school and I suddenly saw it on one of my ACT practice tests. Freaked me out lol but very thorough explanation :)

    I liked this whole video, just got confused on the very last example you provided when you did the math by hand! For those who have a calculator and dunno where the button she's talking about is (I have a TI-83+ so I was confused), after putting the big number go to MATH>PRB>3:nCr>ENTER, then put in the smaller number, hit enter, and you have the answer

    This tutorial is probably a bit more advanced. I understood intuitively why there were slashes and 2's everywhere. Thanks for helping me understand combinations. This is probably the best tutorial i've seen.

    For permutation she explained that making a small group of people from a big one is permutation . But when she solved the problem she used the formula of combination. I’m confused there

    Jesus Christ died for our sins so the devil would not drag us to hell. Jesus tells us to profess with our tongue and believe in our hearts that He is Lord so we can make it to heaven; however, many of us have rejected Him and chose sin. pls come to Christ and reject the true evil: the devil. as long as you believe and walk in His ways, you will reach the Divine Kingdom. God bless you all🥰💞

      Why should we worship Jesus instead of the one who created Jesus?

    • @da9558
      @da9558 3 ปีที่แล้ว

      @@rayyanqureshi8622 bc we'd still be worshipping Jesus. Jesus is God. the Bible (God's Word) teaches that there is only one God. this same God told prophets, such as Isaiah, of a sinless being coming down to die for our sins. Humanity cannot be sinless, so God sent Himself in the flesh (bc we are incapable of looking at God's pure form w/o dying) to die for us. John 10:30 states that Jesus and God are one, and John 10:38 proceeds to say that God is in Jesus and Jesus is in God. the term "Son of God" and "Son of Man" just puts a label on their relationship. I hope that that makes sense :)

      @@nehirmelek7552 "Son of God" is the name of His title on earth. as seen in parts of the Bible, Jesus says He and God are one. I understand that you believe that Jesus is just a prophet, but He is much more than that. the fact that He lived a sinless life already proves that He is more than a prophet. no human being is capable of being sinless.
