Find the varience of the following distribution.

Two statements are given, followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at varience with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements : All bats are sticks. No strick is a ball. Conclusions : I. No bat is ball. II No ball is bat.
