About 26% of movies coming out of Hollywood are comedies. Warner Bros has been the lead studio for about 13% of recent movies, and about 3% of recent movies are comedies from Warner Bros. Let C denote the event a movie is a comedy and W denote the event a movie is produced by Warner Bros. Probabilities based on data from HollywoodMovies. (a) Write probability expressions for each of the three facts given in the first sentence of the exercise. PC)- P(C and W)- Answer 1: exact number, no tolerance Answer 2: exact number, no tolerance Answer *3: exact number, no tolerance (b) What is the probability that a movie is either a comedy or produced by Warner Bros?

a) Probability of comedies P(C)=0.26

Probability of being a Warner movie P(W)=0.13

Probability of being a Warner comedy P(W&C)=0.03

b) The probability that a movie is either a comedy or produced by Warner Bros is P=0.36.

The probability that a movie is either a comedy or produced by Warner Bros is P=0.36.

Option D is correct.

System of equations can be used is given by:

Step-by-step explanation:

here, h represents the weight of the hardcover book, and p represents the weight of the paperback.

As per the given statement: The hardcover version of a book weighs twice as much as its paperback version.

⇒

Also, it is given that the hardcover book and the paperback together weigh 4.2 pounds

⇒

or

Therefore, the system of equations can be used is given by:
