Green balls = 2

Red balls =4

Orange balls =6

total balls =6+4+2

= 12.

• probability = favourable outcomes/total no. of outcomes.

1) probability for orange ball

orange balls=6

total balls =12

so,

probability =6/12 or 1/2.

2) probability for not red .

red balls =4

total balls =12

so, not red balls ==》12 -4 = 8

so,

probability for not red = 8/12 or 2/3.
