Question

each of 180 power tools can be classified as one of three types, as shown in the frequency table. classification type x type y type z frequency 107 6 67 if one of the power tools is selected at random, what is the probability of selecting a power tool of type y? a. $\frac{6}{180}$ b. $\frac{67}{180}$ c. $\frac{107}{180}$ d. $\frac{174}{180}$

Explanation:

Step1: Recall probability formula

The probability $P$ of an event is given by $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$.

Step2: Identify values

The total number of power - tools is $107 + 6+67=180$. The number of type $y$ power - tools is $6$.

Step3: Calculate probability

$P=\frac{6}{180}$

Answer:

a. $\frac{6}{180}$
