If the cardinality of a set A is 4 and that of a set B is 3, then what is the cardinality of the set AUB?

Choose the set of numbers from the four alternative sets, which is similar to the given set. Given set : (224, 15, 4)

Density of the material of a paper is given a 0.5 g cm^(-3) . The mass of the paper is 1 g and its length and breadth are 10 c and 5 cm, respectively. Arrange the following steps in a sequence to find the thickness of the paper. (A). The 0thickness of the paper is ("Volume of the paper (m)")/("Vlume of the paper (V)") (B) The density (d) of the material of the paper is =("Mass of the paper (m)")/("volume of the paper (V)") (C). then the volume (V) o the paper =("Mass of the paper (m)")/("Density (d) of the paper") (D). The volume (V) of the paper is=length xx breadth xx thickness of the paper.

In answering a question on a multiple choice test, a student either knows the answer or guesses. Let 3/4 be the probability that he knows the answer and 1/4 be the probability that he guesses. Assuming that a student who guesses at the answer with probability 1/4. what is the probability that the student knows the answer given that he answers correctly.?

These is an objective type question with 4 answer choices exactly one of which is correct. A student has not studied the topic on which the question has been set. The probility that the student guesses the correct answer is
