A bag contains x red balls, (2x + 8) blue balls and (3x - 15) white balls. a.) Find the total no. of balls in the bag in terms of x. b.) A ball is drawn at random from the bag. Find the probability that the ball is blue (in terms of x). c.) A ball is drawn at random from the bag. Find the probability that the ball is white (in terms of x).

Step-by-step explanation:
Red balls = x
blue balls = 2x+8
white balls =3x-15
Total balls = x+2x+8+3x-15
= 6x-7
Probability of a blue ball = 2x+8/6x-7
Probability of a white ball = 3x-15/6x-7

Answer:
lets go
red balls = x
blue =2x+8
white balls= 3x-15
lets go to deep into the solution
a) Total balls =x+2×+8+3x-15
so total balls =6x-7
b) Probability of blue ball is = 2x+8/6x-7
c) probability of white = 3x-15/6x-7
