Answer:
0.50
Step-by-step 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 :
[tex]=\frac{250}{500}[/tex]
[tex]=0.50[/tex]
Hence the probability that a person consumes 1,500 to 2,000 calories in a day is 0.50.
