Points Which of the following describes a simple event? A. Tossing two coins B. Spinning “lose a turn” on a spinner and drawing a club from a deck of cards C. Rolling an even number on a die and spinning red on a spinner D. Drawing the two of hearts from a deck of cards
The Correct Answer and Explanation is:
Correct Answer: D. Drawing the two of hearts from a deck of cards
Explanation
In probability, a simple event is defined as an outcome or a single result from a probability experiment that cannot be broken down further. It involves only one outcome. To understand which choice represents a simple event, we need to examine each option.
- A. Tossing two coins:
This is not a simple event because it involves two outcomes — one for each coin (e.g., Heads-Heads, Heads-Tails, etc.). It is a compound event, which is made up of two or more simple events. - B. Spinning “lose a turn” on a spinner and drawing a club from a deck of cards:
This is clearly a compound event, as it includes two separate actions happening together — spinning a spinner and drawing a card. Each of these actions has its own set of outcomes, so this is not a simple event. - C. Rolling an even number on a die and spinning red on a spinner:
Again, this is a compound event. It involves rolling a die and spinning a spinner. Even though each action might seem simple on its own, the combination makes it a compound event. - D. Drawing the two of hearts from a deck of cards:
This is a simple event. It describes a single outcome — drawing a specific card (the two of hearts) from a standard deck of 52 cards. It does not involve any additional action or multiple steps. There is only one result being described.
Therefore, option D is the correct answer. It best fits the definition of a simple event in probability — an event with exactly one possible outcome.
