Answer 2

Bag contain black marbel=10

Bag contains white marbel=20

Bag contain blue marbel=5

Therefore total marbel= 20+10+5=35

1. Probability of picking green marbles= $\frac{No.of marbels}{Total marbels}$ =$\frac{0}{35}$ =0 (option a)
2. Probability of picking blue marbles=$\frac{5}{17}$$=\frac{1}{7}$ (option b)
3. Probability of picking white marbles$=\frac{20}{35}$$=\frac{4}{7}$ (option d)
4. Probability of picking black marbles$=\frac{10}{35}=\frac{2}{7}$ (option c)
5. The sun will rise tomorrow= as likely (option a)
6. There will be 4 seasons in the Philippines =as likely (option a)
7. Probability of the coin will land on head=$\frac{1}{2}$ (option b)
8. Probability that the spinner will land on an even number=$\frac{1}{3}$ (option not given)
9. Probability that the spinner will land on a number=1 (option d)
10. Probability that the spinner will land on a number 3=$\frac{1}{7}$ (option b)
