Question

What can be said about the cardinalities of the sample spaces of the events below? event

a.flipping a coin event
b.rolling a standard number cube
a. the cardinality of event a's sample space is 8 greater than event b's.
b. the cardinality of event b's sample space is 8 greater than event a's.
c. the cardinality of event b's sample space is 4 greater than event a's.
d. the cardinality of event a's sample space is 7 greater than event b's?

Answer 1

there 2 possibilities for flipping a coin... heads or tails, so the cardinality is two

rolling a die results in 1,2,3,4,5, or 6, so the cardinality is 6

cardinality (b) is 4 greater than the cardinality (a). answer C
