Answer 1

0.50

Explanation:

Given :

Weight/Calories 1000-1500 1500-2000 2000-2500 Total

per Day

120 lb. 90 80 10 180

145 lb. 35 143 25 203

165 lb. 15 27 75 117

Total 140 250 110 500

Total no. of person consumes 1,500 to 2,000 calories in a day = 250

Total = 500

Now the probability that a person consumes 1,500 to 2,000 calories in a day :

`=(250)/(500)`

`=0.50`

Hence the probability that a person consumes 1,500 to 2,000 calories in a day is 0.50.
