Bearing in mind that, if you multiply any integer whatsoever, by 2, you get an even number, 3*2 or 17*2 or 4*2 and so on.

to get an ODD integer, simply hop once forward of backwards from any even integer, 2-1, or 2+1 or 8+1 or 8-1.

to get a consecutive ODD integer, simply hop twice from any odd integer, say 3+2, or 7+2 and so on.

now, let's pick a reference integer, say hmmm "a".

we know that a * 2, or 2a is an even integer, therefore (2a + 1) is an ODD integer, and (2a +1 ) + 2 is a consecutive odd integer. So, there you have it, our first two odd integers, and the next one, is, you guessed it, (2a + 1) + 2 + 2

so, our three odd consecutive integers are (2a+1), (2a+3) and (2a+5)

so, the triangle has a perimeter of 27, so, let's add them up then

$\bf (2a+1)+(2a+3)+(2a+5)=27\implies 6a+9=27
\\\\\\
6a=18\implies a=\cfrac{18}{6}\implies a=3$

so, our first odd integer is

2a + 1

2(3) + 1 --> 7

and surely you know what the other two are.

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
