Corrected question;
In a group of 65 students 10 have brown eyes and 30 have blue eyes. Find the Probability that a student pick from this group at random either has blue or brown eyes
Step-by-step explanation:
Given;
Total number of students = 65
Number of students with either blue or brown eyes;
= 10+30 = 40

Answer: X=1/4 or X=0.25
Step-by-step explanation:
-3+12x

12x=3
Divide both sides by 12
x=0.25
Answer:
x = -3
