Question

ch 12 you randomly select 500 students and observe that 55 of them are left - handed. estimate the probability that a randomly selected student is left - handed.
0.22
9.09
0.5
0.11

Explanation:

Step1: Recall probability formula

Probability $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

Step2: Identify values

Number of favorable outcomes (left - handed students) $n = 55$, total number of outcomes (total students) $N=500$

Step3: Calculate probability

$P=\frac{n}{N}=\frac{55}{500}= 0.11$

Answer:

0.11
