Question

Find the probability that​ his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more cell phones in​ use? Consider an event to be unlikely if its probability is less than or equal to 0.05.

Answer 1

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
