Darina [25.2K]

Answer:

7:9

Step-by-step explanation:

Number of red balls = 10

Number of green balls = 6

Number of orange balls = 15

Number of blue balls = 14

Total numbers of balls =  45

Probability (odds against the red ball) = P( not red)

P(not red) = P(green) + P (orange) + P (blue)-------------------------  (1)

P (green) = 6/45

P ( orange) =15/45

P (blue)  = 14/45

Substituting in (1)

P(not red) = 6/45 + 15/45+14/45

                =  35/45

                =  7/9

                7:9
