Angelina Cowan · Answer 1

Sample space of the given events contain all the possible outcomes of the event. Cardinality of a set is defined as the number of elements in that set.

For Event A:

The sample space comprises all the 52 outcomes of cards in the deck.

So cardinality of event A = n (A) = 52

For Event B:

The sample space comprises all the 6 outcomes of rolling a dice.

So cardinalty of event B = n (B) = 6

The difference in two is 52 - 6 = 46

So, we can conclude that the cardinality of sample space of event A is 46 more than the event B's sample space.

Thus the correct answer is option A
