A die was rolled 135 times with the results in the table. 

\[\begin{array}{ | c | c | c | c | c | c |c |}\hline \text{Outcome} & 1 & 2 & 3 & 4 & 5&6 \\ \hline \text{Number of times} & 15& 25& 15& 35& 22&23\\ \hline \end{array}\]

a) From looking at the table, are the outcomes likely?
b) What should be the theoretical probability (decimal) of rolling any number?
c) From the table, write the experimental probability of rolling a 3 (as a decimal).
d) From the table, write the experimental probability of rolling an even number (as a decimal).
e) From the table, write the experimental probability of rolling a number greater than 3 (as a decimal).

a) No b) \(0.1\dot{6}\) c) \(0.11 \) d) \(0.61\) e) \(0.59 \)
