Answer:
11.44% probability that exactly 12 members of the sample received a pneumococcal vaccination.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they received a pneumococcal vaccination, or they did not. The probability of an adult receiving a pneumococcal vaccination is independent of other adults. 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.
70% of U.S. adults aged 65 and over have ever received a pneumococcal vaccination.
This means that
20 adults
This means that
Determine the probability that exactly 12 members of the sample received a pneumococcal vaccination.
This is P(X = 12).
11.44% probability that exactly 12 members of the sample received a pneumococcal vaccination.
She will spend $74.25 on gas.
Step-by-step explanation:
Given,
27 miles = 1 gallon
1 mile =
Distance to cover = 892 miles
We will multiply this number with gallons of gas used for 1 mile.
892 miles =
892 miles = 33.04 gallons of gas
Rounding off to nearest whole number;
892 miles = 33 gallons
Cost of one gallon of gas = $2.25
Cost of 33 gallons = 2.25*33 = $74.25
She will spend $74.25 on gas.
