Question

at a sporting event, cheerleaders will throw 50 bundled t - shirts into the crowd. the t - shirt sizes consist of 10 small, 15 medium, and the remainder either large or extra large. suppose ana catches a t - shirt. what is the probability that she will catch a t - shirt that is not a size small? a 0.10 b 0.20 c 0.50 d 0.67 e 0.80

Explanation:

Step1: Calculate the number of non - small T - shirts

Total T - shirts = 50, Number of small T - shirts = 10.
Number of non - small T - shirts \(=50 - 10=40\)

Step2: Calculate the probability

Probability formula \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\)
Here, number of favorable outcomes (non - small T - shirts) = 40, total number of outcomes = 50.
\(P=\frac{40}{50}=0.8\)

Answer:

E. 0.80
