Final answer:
Tavin's activity of tossing a dime and a quarter together 100 times constitutes 100 trials. Each toss is an independent event with equal chances for heads or tails, and the sample space increases with more coins or tosses.
Step-by-step explanation:
The total number of trials Tavin conducted is 100 trials. Each toss of the two coins (a dime and a quarter) counts as one trial, regardless of tossing them simultaneously. Hence, tossing both coins together 100 times results in 100 trials.
When discussing the probability and outcomes of a coin toss, it is essential to understand that each coin toss is an independent event. Therefore, the probability of getting heads or tails on each coin does not change with each toss, and it always remains at 50 percent.
In experiments involving multiple coins or multiple tosses, the individual outcomes can be combined to create a sample space. For instance, if you were to toss three different coins (nickel, dime, and quarter), you would have a larger sample space consisting of all the possible outcomes from each coin.
