In each of the following experiments specify appropriate sample space A person is noting down the number of accidents along a busy highway during a year.
The number of accidents along a busy highway during the year of observation can be either $0$ (for no accident) or $1$ or $2,$ or some other positive integer. Thus, a sample space associated with this experiment is $S =\{0,1,2, \ldots\}$
If three students $A, B, C$ independently solve a problem with probabilitities $\frac{1}{3},\frac{1}{4}$ and $\frac{1}{5}$ respectively, then the probability that the problem will be solved is
