Answer:
28/155
Step-by-step explanation:
To find people who do use the waterslide and/or the sauna subracter 43 from 155 to get 112.
To find the people who only use the sauna subtract 97 from 112 to get 15.
To find people who use both the waterslide and the sauna subtract 15 from 43 to get 28.
The probability of a person who uses both the waterslide and the sauna is 28/155.
The answer is 7x+7/x^2+3x-10
In a standard deck of 52 cards, there are four 8's and four queens. The probability of picking an eight is 4/52 or 1/13. Furthermore, the probability of picking a queen from the deck is also 1/13. Since the problem asked for the probability of picking either eight or queen, add the probability of picking queen and eight. The addition gives 2/13.
Thus, the answer is 2/13.
