Answer:

Event not unlikely

Step-by-step explanation:

Probability is defined as  the likelihood of an event occurring.

[tex]P(E)=Event/Total \ outcomes[/tex]

Total outcome,[tex]T_o[/tex]=Total responses record which is:

[tex]T_o=218+296+362+148+142=1166[/tex]

[tex]P_e=142[/tex]

Therefore the probability of 4+ phones is

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

Since [tex]0.1218>0.05[/tex], the event is not unlikely
