Find the total number of balls:
Red balls: 4
Green balls: 4
Blue balls: 6
Total balls: 4 + 4 + 6 = 14
Find the number of red or blue balls:
Red balls: 4
Blue balls: 6
Red or blue balls: 4 + 6 = 10
Calculate the probability:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
Probability (red or blue) = 10 / 14
Simplify the fraction:
10 / 14 = 5 / 7
Answer:
The probability of drawing a red or blue ball is 5/7.
