hello,
red balls are 4 and blue balls are x
total no. of balls are x+4
given that probability of getting a blue ball is 1/2
therefore,1/2=x(blue ball)/x+4(total no. of balls)
1/2=x/x+4
x+4=2x
4=2x-x
4=x
therefore,blue balls in the bag are 4 balls
hope this helps,if u like it please mark it as brainliest
