cool down: oh, deer
forest rangers record information about some of the deer in the forest they oversee. use the two - way table to answer the questions about the deer they observed.

1. how many of the observed deer younger than 1 year old have antlers?
2. how many of the observed deer are 1 year old or older?
3. how many different deer are included in the table?

Explanation:

Step1: Find the value for deer younger than 1 year old with antlers

Look at the intersection of the "antlers" row and "younger than 1 year old" column. The value is \(0\).

Step2: Calculate the number of deer 1 year old or older

Add the values in the "1 year old or older" column. \(12 + 15=27\).

Step3: Calculate the total number of deer

Add all the values in the table. \(0+12 + 23+15=(0 + 12)+(23 + 15)=12+38 = 50\).

Answer:

1. \(0\)
2. \(27\)
3. \(50\)
