Answer:

Step-by-step explanation:

p (event happening) = no. of desired outcomes ÷ total no. of outcome

Q. 7. a) p (red ball) = no of red balls ÷ total no of balls

                                = 4 ÷ (4+5+3)

                                = 4 ÷ 12

                                = 1 ÷ 3

Q. 7. b) p (white ball) = no of white balls ÷ total no of balls

                                = 3 ÷ (4+5+3)

                                = 3 ÷ 12

                                = 1 ÷ 4

Q. 7. c) p (yellow ball) = no of yellow balls ÷ total no of balls

                                = 5 ÷ (4+5+3)

                                = 5 ÷ 12
