**Solution:** Total number of outcomes = 5 + 8 + 4 = 17

Number of red marbles = 5

Number of white marbles = 8

Number of green marbles = 4

**(i) Red?**

**Solution:** Probability of red marbles;

P(R) = 5/17

**(ii) White?**

**Solution:** Probability of white marbles;

P(W) = 8/17

**(iii) Not green?**

**Solution:** Probability of green marbles;

P(G) = 4/17

Or, P( not G)

= 1 - 4/17

=13/17
