Mohamed Rollins · Answer 1

Option C. The cardinality of event B's sample space is 4 greater than event A's.

Step-by-step explanation:

The cardinality of of the sample spaces of the events means that, the number of possible outcomes of an event.

Here there are two events,

Event A: Flipping a coin

Event B: Rolling a standard number cube

Cardinality of event A

In the case of event A, number of possible outcomes are Head and Tail

cardinality = 2

Cardinality of event B

In the case of event A, number of possible outcomes are 1,2,3,4,5, and 6

cardinality = 6

The cardinality of event B's sample space is 4 greater than event A's.

Therefore the correct answer is option C
