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 sport if correct free brainy and follow or sub on any platform

19

Step-by-step explanation:

140 in group - 81 that play a sport = 59 left.

Out of 59 left - 40 who dont play a sport at all = 19 left

19 of the 92 who watch tennis dont play a/the sport.

11/92

Step-by-step explanation:

40 out of 140 neither watch tennis nor play a sport

100 left

81 out of 100 play a sport and 92 watch tennis, so 81 out of 100 both play a sport and watch tennis

92-81 = 11 out of 92 who watch tennis don't play a sport

So required probability is 11/92
