Number one two and four are true
1. 3+5=8 and 8 is 80% of ten
2.the prob of drawing a red marble in the first go is 3/10 x 5/9 (for the probabilty of drawing a green one in the second go) =1/6

3. The probability OF drawing a blue marble is 20% (hence false)

4. 3+2 = 5, the same amount of red and blue marbles together as of green ones
