Answer:
0.9744 probability that AT LEAST ONE of them has been vaccinated
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have been vaccinated, or they have not. The probability of a person having been vaccinated is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
60% of the people have been vaccinated.
This means that 
If 4 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated?
This is
when
.
We have that

In which



0.9744 probability that AT LEAST ONE of them has been vaccinated
Answer:
We use negative values for the money Arleen spends.
a) We determine the change to the value on her gift card:
4(-35)+(-9)= -140+(-9)=-149
b) We determine the amount on money she has left on the gift card after renting the tiller and buying the rake:
200+(-149)=51
Since she has got $51 on her gift card and a wheelbarrow is $50 she is able to buy it:
51>50
RESULT
a) -$149 less b) yes

Answer:
Step-by-step explanation:
pythagorean theorem
12^2 + 5^2 = PQ^2
144 + 25 = 169
= 13
answer = 13 units
