It is useful for Fire Departments to have a model for X=number of direct injuries occurring in a fire incident. They can use this to determine the level of medical services to make available each time.  Suppose the pmf of X is as follows:       x          0       1       2       3       4       5       6       7       8       9          f(x)       .08    .09    .09    .14    .18    .16    .09    .06    .06    .05       Use this pmf to determine the probabilities of the following events: event that there will be at least 1 direct injury event that there will less than 3 direct injuries event that there will be more than 2 but less than 8 direct injuries
