Eight of the first twenty numbers are prime, so the probability is 8/20 or 0.4 .

Is 1 a prime number


No, 1 is not a prime number. The decomposition of a number into prime factors must be unique so 2=1x2 is prime but since 1 can be written as 1=1x1x1x1....x1 with an arbitrary number of factors this opens up a can of worms as far as unicity of the decomposition is concerned. Conclusion: 1 has been ruled out as a prime number.
I hope that this gives you an idea why 1 is no longer considered prime.

How do I generate a random number that is greater than 1 on a casio fx-300MS


The random number function always generates a number between zero and one. You can convert this to a random number in any range by a suitable combination of multiplications and additions. For example, if you want a random number between zero and ten, multiply the generated random number by 10. If you want a random number between one and ten, multiply the generated random number by 9 and then add 1.

If you want to simulate the roll of a six-sided die, multiply the generated random number by 6, add 1, and ignore the fractional portion. This will give you a 1, 2, 3, 4, 5, or 6 with more-or-less equal probability.

How do i generate random integers with a ti 89 titanium?


Use the rand() function. If you give it a positive integer argument n, it will return a random integer in the range in the interval [1, n]. You'll find rand() in the MATH/PROBABILITY menu.

What is the probability of rolling a even number or a prime number on a number cube? write fraction in simplest form


even nos: 2,4,6

prime nos:2,3,5

ie 1 is the only no. which is not desired

probability of getting one=1/6

hence probability of getting either even or prime no is
= 1-1/6 = 5/6

Generate a random number


Press the math key. Arrow over to PRB (probability) Select #5 randInt. You will now be at the home screen. From here you have to let the calculators the set of numbers you want to use. For example if you want to use the numbers 1 thru 50 type in 1,50. You must separate the numbers with a comma. Then press enter as many time as you want to generate a random number. It is not necessary.to end the parentheses.

How do I get the Ti 85 to do random integers?


Functions on the calculator are bold. Numbers you choose are in italics.

For random positive integers between 0 and n use the following:

int (rand * n) + 1


int is on [Math] [Num] F4

and rand is on [Math] [Prob] F4

rand returns a random number x between 0 and 1 such that 0 < x < 1.

int returns the integer portion of a number such that int 123.456 returns 123 and int -123.456 returns -124.
