Question

maggie goes into a dark room and randomly grabs a hair tie from a drawer of 10 red, 20 blue, and 20 black ties. what is the probability of picking a red hair tie? 20% 15% 40% 10%

Explanation:

Step1: Calculate total number of hair ties

Total = \(10 + 20+20=50\)

Step2: Calculate probability of picking red hair tie

Probability \(P=\frac{\text{Number of red hair ties}}{\text{Total number of hair ties}}=\frac{10}{50} = 0.2\)
Convert to percentage: \(0.2\times100\% = 20\%\)

Answer:

20%
