pants express sells juniors jeans in different sizes and lengths. the table shows the options they have available. what is the probability that the customer will choose size 7 or 9 in regular length?
sizes length
7 petite
9 regular
11 tall
a $\frac{1}{3}$
b $\frac{2}{9}$
c $\frac{1}{9}$
d $\frac{1}{6}$

Explanation:

Step1: Find total possible outcomes

Calculate total combinations: $3 \text{ sizes} \times 3 \text{ lengths} = 9$

Step2: Identify favorable outcomes

Favorable pairs: (7, Regular), (9, Regular) → total 2

Step3: Calculate probability

Probability = $\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}} = \frac{2}{9}$

Answer:

B. $\frac{2}{9}$
