A bag consists of 10 balls each marked with one e digits 0 to 9. If four balls are drawn successively with replacement from the bag, what is the probability that none is marked with the digit 0?

Let E and F be two independent events. The probability that exactly one of them occurs is 11/25 and the probability if none of them occurring is 2/25 . If P(T) denotes the probability of occurrence of the event T , then (a) P(E)=4/5,P(F)=3/5 (b) P(E)=1/5,P(F)=2/5 (c) P(E)=2/5,P(F)=1/5 (d) P(E)=3/5,P(F)=4/5

A sample space consists of 9 elementary outcomes outcomes E_(1), E_(2),…, E_(9) whose probabilities are: P(E_(1)) = P(E_(2)) = 0.09, P(E_(3))=P(E_(4))=P(E_(5))=0.1, P(E_(6)) = P(E_(7)) = 0.2, P(E_(8)) = P(E_(9)) = 0.06 If A = {E_(1), E_(5), E_(8)}, B= {E_(2), E_(5), E_(8), E_(9)} then (a) Calculate P(A), P(B) , and P(A nn B) . (b) Using the addition law of probability, calculate P(A uu B) . (c ) List the composition of the event A uu B , and calculate P(A uu B) by adding the probabilities of the elementary outcomes. (d) Calculate P(barB) from P(B) , also calculate P(barB) directly from the elementarty outcomes of B .
