The events of Madelyn picking a crayon and then her little brother picking a crayon are dependent events. This is because the outcome of Madelyn's choice affects the options available for her little brother. If Madelyn picks a crayon first, that crayon is no longer available for her little brother to choose from, which influences his selection. Thus, the probability of her brother's choice is influenced by Madelyn's choice.
Madelyn and her little brother are coloring. Madelyn picks a crayon from the box and then her little brother picks one.
Are these two events dependent or independent?
