Step-by-step explanation:
Given that events are as follows:
A: A green ball is drawn from a box with five balls and placed next to the box. B: A red ball is drawn next and placed next to the green one
i.e. drawings of balls are made without replacement
Suppose there are m green balls and n red balls, where m+n =5
Prob of drawing green ball =m/5
After I draw made remaining are n red balls and m-1 green balls
Prob of drawing red ball now =n/4
Prob for drawing one green and one red simultaneously =
Product of the two probabilities =
