An experiment is performed 30 times, and an event

E

does not occur in any of the trials. Which statement is correct? (a)

P(E)=\dfrac{1}{30}

and

E

is a rare event. (b)

0<P(E)<1

because

E

might occur next time. (c)

P(E)=0

and

E

is an impossible event. (d)

P(E)=\dfrac{29}{30}

since

E

failed to occur in

29

out of

30

trials.
