In one town, 47% of all voters are Democrats. If three voters are randomly selected for a survey, what is the
probability that they are all Democrats?

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

Step-by-step explanation:

Step(i):-

Given that the all voters are democrats

The probability that the all voters are democrats

p = 47% =0.47

q = 1-p =1-0.47 = 0.53

Step(ii):-

Let 'X' be the random variable in binomial distribution

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

n=3 and r=3

P(X=3) = 0.1038

Final -

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

26

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
