(i) Red
Total numbers of red marbles = 5
Number of white marbles = 8
Number of green marbles = 4
Total number of marbles = 5 + 8 + 4 = 17
Probability of getting a red marble is = Total number of red marbles/Total number of marbles
= 5/17
∴ Probability of getting a red marble is 5/17
(ii) White
Total numbers of red marbles = 5
Number of white marbles = 8
Number of green marbles = 4
Total number of marbles = 5 + 8 + 4 = 17
Probability of getting a white marble is = Total number of white marbles/Total number of marbles
= 8/17
∴ Probability of getting a white marble is 8/17
(iii) Not green
Total numbers of red marbles = 5
Number of white marbles = 8
Number of green marbles = 4
Total number of marbles = 5 + 8 + 4 = 17
Total number of non-green marbles = 5 + 8 = 13
Probability of getting a non-green marble is = Total number of non-green marbles/Total number of marbles
= 13/17
∴ Probability of getting a non-green marble is 13/17
