What is the probability that a number chosen at random from the 2, 4,5 and 6 times tables (up to the 12th multiple) is either a multiple of 3, prime or a
square number?

I have set this table up in a spreadsheet and colored in the squares as they appear in the table above. I have not counted any number as a member of 2 categories twice. An example would be 36 which is a multiple of 3 and a perfect square.

I have answered the question as though the question took on the properties of a dart board: you through a dart and whatever you hit is counted either as prime, a multiple of 3 or a perfect square

That said, there are

primes:                    2

multiples of 3:       24

Perfect squares:      4

Total number of choices: 12*4 = 48

Probability: 30 / 48 = 5/8 or 0.625

If you are supposed to use some other method of counting, please leave a note.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
