You have a standard deck of cards (52 cards). What is the probability you draw a four from the deck, do not replace the card, and then draw a face card (Jack, Queen,
King)?

Work Shown:

A = event of drawing a four from the deck

P(A) = 4/52, because there are 4 cards labeled "4" out of 52 total

B = event of drawing a face card on the second draw given the previous card was a "4"

P(B) = 12/51, there are 3 face cards per suit so 4*3 = 12 face cards total. There are 52-1 = 51 cards after we picked the first card and did not put it back.

P(A and B) = P(A)*P(B)

P(A and B) = (4/52)*(12/51)

P(A and B) = (4*12)/(52*51)

P(A and B) = 48/2652

P(A and B) = (4*12)/(4*221)

P(A and B) = 4/221

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
