Question

the two - way frequency table shows the current inventory of hardwood that a lumberyard carries. suppose a customer randomly selects a board from the lumberyards inventory. use the table to calculate each probability. round to the nearest tenth of a percent if necessary. sample problem p(oak) 62/210≈0.295 = 29.5% p(maple and 1×3) > enter the answer in the space provided. use numbers instead of words.

Explanation:

Step1: Identify favorable and total counts

The number of maple and 1×3 boards is 28. The total number of boards is 210.

Step2: Calculate probability

The probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{maple and }1\times3)=\frac{28}{210}$.

Step3: Convert to percentage

$\frac{28}{210}\approx0.133$. To convert to a percentage, multiply by 100: $0.133\times 100 = 13.3\%$.

Answer:

$13.3$
