Question

quantitative reasoning. instructions: choose the best answer. if necessary, use the paper you were given. question: patrick has 4 green hats, 3 blue hats, and 1 orange hat. if he selects a hat at random, what is the probability of selecting a green hat? 0.3 0.4 0.5 0.8

Explanation:

Step1: Calculate total number of hats

The total number of hats is the sum of green, blue and orange hats. So, $4 + 3+1=8$ hats.

Step2: Calculate probability of selecting green hat

The probability $P$ of an event is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. The number of favorable outcomes (selecting a green hat) is 4, and the total number of outcomes (selecting any hat) is 8. So, $P = \frac{4}{8}=0.5$.

Answer:

0.5
