What is the definition of theoretical probability?
Theoretical probability is the probability of an event when all outcomes are equally likely. With theoretical probability, you determine the probability by dividing the number of ways the event can occur by the total number of equally likely outcomes.
How many ways can you arrange 36 squares in equal rows?
Oh, dude, arranging 36 squares in equal rows? That's like asking how many ways you can arrange your socks in a drawer. Technically, you can arrange them in 36! ways, which is a super big number that I'm too lazy to calculate. So yeah, have fun with your square arranging adventures!
How many ways can the letters in Toronto be arranged?
There are 7 letters, but three 'o's are indistinguishable, so there are 7! ÷ 3! ways = 840 ways. If the 'T' and the 't' are also considered to be indistinguishable (that is ignoring the case of the letters; making "Toronto" and "toronTo", etc the same), then the number of ways is 7! ÷ (3! x 2!) ways = 420 ways. ! after a number means the factorial of the number which is the product of all numbers less than or equal to the number, and greater than or equal to 1. Thus: 7! = 7 x 6 x 5 x 4 x 3 x 2 x 1. 3! = 3 x 2 x 1 2! = 2 x 1 0! is defined to be 1.
How many ways are there to write a 3 digit positive integer using digits 1 3 5 7 and 9 if no digit is used more than once?
This is a question of permutations; the answer is equal to the factorial of 5 (number of digits) divided by the factorial of 3 (number used in each selection), written 5! / 3!. This equals 120 / 6, or 20 ways.
