A school band sold 30 raffle tickets, each labeled with a number from 1 to 30. One winning ticket will be drawn.

Answer 1

need help

Answer 2

what i can guess

Answer 3

wait

Answer 4

4/15

Answer 5

There are 7 numbers from 1 to 30 that are multiples of 4: 4, 8, 12, 16, 20, 24, 28

So there are 8 ways that a number can be 19 or a multiple of 4.

So the probability of that is 8/30, which is 4/15 in simplest form.

Answer 6

how many multiples of 4 are there between 1 and 30 ?
4, 8, 12, 16, 20, 24, 28
there are 7 multiples of 4 and 1 number 19
there are 8 ways to win
P=8/30=4/15

7 tickets = multiples of 4 (4,8,12,16,20,24,28)
1 ticket = 19
therefore:

P(multiple of 4 or 19) = 7+1 / 30
= 8/30
= 4/15
... think that's the simplest fraction you'll get, you can work that out in decimals or % tho if u like?
