Step-by-step explanation:
Answer – B (Tossing a coin)
A simple event is an event where only one experiment happens at a time (such as tossing a coin), and the event has only one outcome. When two events are occurring simultaneously(such as spinning a spinner and drawing a card from a deck of cards, drawing 3 cards from a deck of cards or tossing 4 coins), then it is no longer a simple event; it is a complex event.

Answer:
And using the property of symmetry for the confidence interval we can estimate the sample proportion with this formula:
The final answer for this case would be:
So approximately 15% of teenagers have a sibling.
Step-by-step explanation:
For this case we assume that the proportion of interest is who represent the number of teenagers who have a sibling and in order to estimate this proportion we can conduct a confidence interval.
The confidence interval for the mean is given by the following formula:
And for this case the confidence interval is given by:
And using the property of symmetry for the confidence interval we can estimate the sample proportion with this formula:
The final answer for this case would be:
So approximately 15% of teenagers have a sibling.
Your answer would be 12.
She can use 12 connecting cubes to make the model in only two ways.
