Question

In an office ,where 42 staff members work ,7 staff members use cars , 20 staff members use bikes and the remaining 15 members use cycles . find the probability of cycles users

Answer 1

Answer:

I think the answer must be 15/42........

Answer 2

Answer:

Total no. of staff = 42

Let the event of a staff member using cycles be 'E'

P(E) = No. of trials in which the event has occured

         ---------------------------------------------------------------

                           Total no. of trials

P(E) = No. of staff member using cycles

       ---------------------------------------------------

                     Total no. of staff

       =   15

          ------

            24

      =    5

          ------  

            8

∴ The proability of cycle users =  $\frac{5}{8}$
