Amath teacher randomly selects one student in a class to write a probability question on a chalkboard. the teacher then randomly selects a different student to answer the probability question. there are 12 boys in the class, and the ratio of boys to girls is 2: 3. find the probability that the teacher selects a girl first and a girl second. write your answer as a decimal rounded to the nearest thousandth.

The probability that the teacher selects a girl first and a girl second is 0.352

Step-by-step explanation:

Number of boys in class = 12

let number of boys in class = 2x

number of girls in class = 3x

According to the question,

2x = 12

x = 6

So, number of girls = 3x = 3 × 6 = 18

Total number of students = 18 + 12 = 30

Probability of selecting a girl first and second girl =

Therefore, The probability that the teacher selects a girl first and a girl second is 0.352
