Final answer:
Approximately d) 40 percent of all marriages involve a remarriage of one or both partners, mostly after a previous divorce, with variations in remarriage rates among different racial groups.
Step-by-step explanation:
Today, approximately 40 percent of all marriages involve a remarriage of one or both partners. This is found by adding the percentage of all married couples involving one partner who is in their second marriage (15%) and those couples where both partners are in a second marriage (9%), as reported by the U.S. Census Bureau in 2015.
Moreover, the majority of these remarriages occur after a divorce rather than the death of a spouse, with 91 percent following divorce. The pattern among different races also shows variations, with White individuals being more likely to remarry than Black individuals.
