The probability of drawing a marble will be either red or blue is 52%
Step-by-step explanation:
Given,
Number of red marbles = 5
Number of blue marbles = 8
Number of green marbles = 12
Total number of balls = 25
To find the probability( either a red or blue marble)
Formula
Probability( either a red or blue marble) = P( red) + P(blue)
=[tex]\frac{5}{25} +\frac{8}{25}[/tex]
= [tex]\frac{13}{25}[/tex]
Hence, the probability is = [tex]\frac{13}{25}[/tex]×100 = 52%
