Question

rob owns 6 green t - shirts and 15 t - shirts in other colors. if rob randomly selects a t - shirt to wear, what is the probability it will be green? write your answer as a fraction or whole number. p(green) =

Explanation:

Step1: Calculate total T - shirts

$6 + 15=21$

Step2: Calculate probability of green T - shirt

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, the number of favorable outcomes (green T - shirts) is 6 and the total number of outcomes (total T - shirts) is 21. So $P(\text{green})=\frac{6}{21}=\frac{2}{7}$

Answer:

$\frac{2}{7}$
