Let's split the problem in non-intersecting subsets: we have good wood racquets,
defective wood rackets,
good graphite racquets,
defective graphite rackets.
The probability that the racket is wood or defective covers the following subsets: good wood, defective wood and defective graphite, which have, respectively, ,
and
elements.
Since the total is elements, the probability is
Hello there! I am EnjoyingLife, and I hope you find my answer helpful.
First of all, since all books cost less than $5, the most expensive a book could be is $4.99 (remember, less than, not less than or equal to)
Now, let's write an inequality to represent the cost of books.
We know that all books cost less than $5.
We have a sign for "less than". It's "<"
Thus,
p<5
Hope it helps!
Have an awesome day!
Good luck!
