Consider two events such that p(a)=1/4, p(b)=2/5, and p(a∩b)=1/10. are events a and b independent events?

yes, they are independent because p(a)×p(b)=p(a∩b)

no, they are dependent because p(a)×p(b)=p(a∩b)

no, they are dependent because p(a)×p(b)≠p(a∩b)

yes, they are independent because p(a)×p(b)≠p(a∩b)
