If there is a 40% chance that a bowler will get a strike, then the chance that the bowler will not get a strike can be calculated as follows:
\[ \text{Probability of not getting a strike} = 100% - \text{Probability of getting a strike} \]
\[ \text{Probability of not getting a strike} = 100% - 40% = 60% \]
So, the probability is 60%.
