Let's attribute a to equal probability of 2 and b to equal probability of 3 A=54/360 B=62/360 "or" means you combine the probabilities which means that AvB =116/360 now simply divide 116 by 360 and you get your answer which is 0.32 A is the correct answer my dude
The Bessel function or order zero of the first kind may be defined by the solution - to Bessel's differential equation - which is a finite value at the origin X=0 for positive or negative whole numbers (integers) or positive alpha (α) values.
