Answer 2

Answer:

P( green or blue) = 9/20

P( green, yellow or blue)  = 3/4

P( green,  red or blue)  = 7/10

Step-by-step explanation:

There are 40 slips in all, Green: 15, Red: 10, Blue: 3, Yellow: 12.

P( green or blue) = green or blue / total

                            = (15 + 3)/ 40

                            = 18/40

                             = 9/20

P( green, yellow or blue) = green yellow or blue / total

                            = (15+12 + 3)/ 40

                            = 30/40

                             = 3/4

P( green, red or blue) = green  red or blue / total

                            = (15+10 + 3)/ 40

                            = 28/40

                             = 7/10
