Answer:
a)
table:
[tex]\begin{array}{ccccc}&2&3&4\\0&2&3&4\\1&3&4&5\\2&4&5&6\\3&5&6&7\end{array}[/tex]
b) Count the number of occurrances:
i: There are 3 fours in the table of 12 outcomes, so the probability is 3/12 = 1/4
ii: There are 9 outcomes less than six in the table of 12 outcomes, so the probability is 9/12 = 3/4
iii: There are 3 outcomes of 6 or more in the table of 12 outcomes, so the probability is 3/12 = 1/4
