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.

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

step-by-step explanation:

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

actually what is a question i don't understand
