Suppose on a CD, you like 10 out of 13 songs. If you randomly select four songs to be played once, what is the probability that (a) You like 3 of the songs out of the 4? Enter your answer rounded to two decimals. (b) You like the first two songs and then dislike the second two songs, in that order? Enter your answer rounded to two decimals.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
Suppose on a CD, you like 10 out of 13 songs. If you randomly select four songs to be played once, what is the probability that
(a) You like 3 of the songs out of the 4? Enter your answer rounded to two decimals.
(b) You like the first two songs and then dislike the second two songs, in that order? Enter your answer rounded to two decimals.
