Events a and b are disjointed. p(a) =1/10 p(b) =3/10 find p(a or b).

1.3/10
2.3/100
3.3/20
4.2/3

The answer will be 4

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
