Question

A number is chosen at random from the set £1,2,3,4......18...24....30 find the probability that it is( A) either a factor of 18 or a multiply of 6( b) either a multiple of 5 or a factorof 2( c) nither a factor of 8 nor 12

Answer 1

Please am waiting for the answer to the questions I need it please

Answer 2

this just like the COMPUTER problem.
You apparently have 30 numbers to choose from.
So count the ways to pick a desired number, and divide that by 24 to get the probability of picking one of the desired choices.
(sometimes it might be easier -- as in (c) -- to count the ways to fail, and then just subtract that from 24 to get the ones you want)

Answer 3

Please help me show working thanks

Answer 4

come on ... For the first one,
factors of 18: 1,2,3,6,9,18
multiples of 6: 6,12,18
total choices: 7
so P = 7/24

I'm sure you can follow these steps on the others.
