    Answer:

    Event not unlikely

    Step-by-step explanation:

    Probability is defined as  the likelihood of an event occurring.

    P(E)=Event/Total \ outcomes

    Total outcome,T_o=Total responses record which is:

    T_o=218+296+362+148+142=1166

    P_e=142

    Therefore the probability of 4+ phones is

    P(x\geq 4)=142/1166=0.1218

    Since 0.1218>0.05, the event is not unlikely
