Question

In a group of 140, 92 watch tennis, 81 play a sport, and 40 do neither. Find the probability that an adult chosen at random from those who watch tennis does not play a sport.

a) 9/92
b) 40/92
c) 51/92
d) 81/92

Answer 1

The probability that an adult chosen at random from those who watch tennis does not play a sport is 11/92.

Step-by-step explanation:

To find the probability that an adult chosen at random from those who watch tennis does not play a sport, we need to find the number of adults who watch tennis and do not play a sport, and divide it by the total number of adults who watch tennis.

From the given information, we know that there are 92 adults who watch tennis, and 81 adults who play a sport. Since 40 adults do neither, we can subtract the number of adults who play a sport from the total number of adults who watch tennis to find the number of adults who watch tennis but do not play a sport: 92 - 81 = 11.

Therefore, the probability of selecting an adult who watches tennis and does not play a sport is 11/92.
