Answer:
The type of sampling used in the given statement is simple random sampling.
<u>Simple random sampling:</u> This is the type of probability sampling. In this type of sampling each and every unit of the population has an equal chance of being included in the sample. There are various of methods of choosing the sample randomly such as lottery method, use of random number tables, use of computers to generate random numbers etc.
In the given example, a pollster uses a computer to generate the random numbers and interviews the voters corresponding to those random numbers. Therefore, the method used here is simple random sampling.
Connecticut as a permutation, 1 example would be c1,o,n1,n2,e,c2,t1,I,c3,u,t2. 10 items can form 10! permutations. Considering c1=c2=c3, n1=n2, t1=t2, let’s look at the c all equal condition: 3cs existing one in front of or behind another may form c1, c2, c3; c1, c3, c2; c2,c1,c3… totally 6 different ôkkkiojobvarieties

Answer:
2.5 times per hour, on average
{0:00, 0:24, 0:48, 1:12, 1:36} then repeating at 2:00
Step-by-step explanation:
The least common multiple of the intervals is ...
LCM(8, 12) = 8·12/GCD(8, 12) = 8·12/4 = 24
The two buses will stop at the same time every 24 minutes. That is 60/24 = 2.5 times per hour.
Starting with the 6:00 am stop, the next joint stop is at 6:24, then 6:48. In the next hour, the stops are at 7:12 and 7:36. This sequence of times repeats, starting at 8:00 am. That is, the cycle repeats every 2 hours.
