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

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
