Based on the u. s. census bureau’s american community survey of 2017, 12.9% of the u. s. population was foreign-born. the u. s. census bureau uses the term foreign-born to refer to anyone who is not a u. s. citizen at birth. when i took a sample of 5 students from my statistics class find the following probabilities:

1 find the probability that none of the students are foreign-born (x=0)
2 find p(x> =1) (that at least one is foreign-born)

0.52474, 0.47526

Step-by-step explanation:

given that based in the U.S. Census Bureau’s American Community Survey of 2017, 12.9% of the U.S. population was foreign-born.

The U.S. Census Bureau uses the term foreign-born to refer to anyone who is not a U.S. citizen at birth.

Hence for a randomly selected citizen to be foreign born has constant probability 12.9% since each person is independent of the other and there are only two outcomes.

For the sample of 5 students, X = foreign born is binomial (5, 0.129)

1) the probability that none of the students are foreign-born (x=0)

=

2 p(x>=1) (that at least one is foreign-born)

=

their are no angles. sorry cant .

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

non hispanic white population

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
