There are 25 balls in the box, 7 of them are white 9 are black and the rest are the colors of the rainbow. What is the probability of pulling out a rainbow-colored ball?

The total number of outcomes equal to the number of balls: n = 25;
The number of favorable outcomes equal to the number of rainbow colored balls: m = 25 – 7 – 9 = 9;
Probability of pulling a rainbow-colored ball:
P = m / n = 9/25 = 0.36;
Answer: The probability that the ball taken out will be the color of the rainbow is 0.36;
