Complete Question

Kelvin finished 2/3​​ of his test in a 1/2​​ hour. Express this rate in hours per test.

Answer:

Evgen [1.6K]

Answer:

30/1000

Step-by-step explanation:

red has a chance of 3/10

purple has a chance of 2/10

yellow has a chance of 5/10

for probability, multiply the denominators together, and the numerators together

3*2*5 = 30

10*10*10 = 1000

So the probability of picking red, then purple, and then yellow with replacement is 30 of 1000

Hope this helps!

Salsk061 [2.6K]

Answer:

CASI

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

Sample survey questions are usually read from a computer screen. In a computer-aided personal interview (CAPI), the interviewer reads the questions and enters the responses. In a computer-aided self interview (CASI), the interviewer stands aside and the respondent reads the questions and enters responses. One method almost always shows a higher percent of subjects admitting use of illegal drugs.

This is because they get to interact with a computer rather than a human interviewer.
