Affordable: I really do think you’re getting value for money here.But, I feel there are a few flaws in this: first, if you’ve got your smart phone on you, why not just use a website to generate the graph in the first place? Second, if you are going to be generating graphs regularly in class, you really should get yourself a graphing calculator! QR Code for Graphs: It’s a clever idea to be able to scan a QR code on your smart phone to generate graphs using this calculator (it means you can use it as a graphing calculator at a stretch).Very Visual: As a visual learner, I love that this calculator has clear visual menus, spreadsheet function and graphical representations of differentials, integrals, etc.I also think the spreadsheet function is second to none in the scientific calculator range. – again, this really helps me as a visual learner. I love how it can do graphical representations of differentials, integrals, etc. It can also do 4×4 matrices, which is a step up from the old 3×3 in the older model. It has a significantly improved screen resolution than its predecessor (4 timed better than the ES model) which enabled Casio to develop a much more visual menu feel. For me as a very visual learner this was perfect. I quickly feel in love with this calculator. Quick Review: Beautiful screen, very visual, and a great range of functions for a very low cost. Helect 2-Line Engineering Scientific CalculatorĪ very affordable basic calculator for middle & high school general math. ( Check Today’s Price on Amazon)Ī decent cheap calculator, but not as good value as the Casio fx-991EX. This is the scientific calculator you’ll need if you’re doing the GED exams, but not the best for college. ( Check Today’s Price on Amazon)Ī sturdy calculator with logical interface design and well spaced-out buttons. One of my favorite scientific calculators and a good alternative to the Casio FX-991EX. ( Check Today’s Price on Amazon)Īffordable and easy to use. ( Check Today’s Price on Amazon)Ī quality scientific calculator at a good price point. The probability that the banker will meet with less than 9 people before encountering someone who is filing for bankruptcy is 0.307466.īonus: Feel free to use this online geometric distribution calculator to confirm your results.Final Thoughts Best Scientific Calculators for Students #īeautiful screen, very visual, and a great range of functions for a very low cost. Scroll down to geometcdf() and press ENTER. To answer this, we can use the geometcdf() function. What is the probability that the banker will meet with less than 9 people before encountering someone who is filing for bankruptcy? Suppose it’s known that 4% of individuals who visit a certain banker are visiting to file bankruptcy. The probability that the fourth person the researcher talks to is the first person to support the law is 0.1024. Then type in the following values and press ENTER. Scroll down to geometpdf() and press ENTER. To answer this, we can use the geometpdf() function. What is the probability that the fourth person the researcher talks to is the first person to support the law? The probability that a given person supports the law is p = 0.2. Suppose a researcher is waiting outside of a library to ask people if they support a certain law. The following examples show how to use each of these functions in practice. To calculate probabilities related to the geometric distribution on a TI-84 calculator, we can use the following functions: The cumulative probability that we experience k or less failures until the first success can be found by using the following formula:
