Event a: lands on an even number event b: lands on purple events a and b are (pic for first question) event a: lands on yellow event b: lands on green events a and b are (pic for second question)

1. you have a circle divided into 6 equal parts, numbered from 1 to six and coloured in six different colours.event a: lands on an even number (this may be 2, 4, 6) event b: lands on purple (only 1 purple sector with number 2)events a and b are dependent (may land on sector 2, which is purple and has even number).2. you have a circle divided into 4 equal parts, coloured in four different colours.event a: lands on yellow event b: lands on green events a and b are independent (yellow and green sectors are disjoint, thus if  lands on yellow, than doesn't land on green and vice versa).
