1.If 0 and 1 are the only possible values of the random variable X, and if P(0) = P(1)= 0.8, is a probability distribution defined?*

No, because P(0)+P(1)>1

Yes, because P(0) and P(1) are both less than 1

No, because [P(1)][P(0)]>1

Yes, since P(0)+P(1)>1

2.If 0 and 1 are the only possible values of the random variable X, and if P(0) = P(1)= 0.8, is a probability distribution defined?*

No, because [P(1)][P(0)]>1

Yes, since P(0)+P(1)>1

Yes, because P(0) and P(1) are both less than 1

No, because P(0)+P(1)>1
