Math Problem Statement
Marissa conducted an experiment where she pulled a number out of a bag, then flipped a coin. The bag contained card with the number 1 to 5 written on them. Marissa recorded that out of 60 trials, she pulled the number 2, then flipped tails 15% of the time.
How many times did Marissa pull the number 2, then flip tails?
__________ times
Solution
To determine how many times Marissa pulled the number 2 and then flipped tails, we use the given percentage.
We know that:
- There were 60 total trials
- The event of pulling 2 and flipping tails happened 15% of the time
Step 1: Compute the number of times this event occurred
Thus, Marissa pulled the number 2, then flipped tails 9 times.
Do you want me to break it down further or provide alternative methods?
Here are five related questions to expand on this concept:
- If Marissa pulled the number 2 25% of the time, how many times did she pull it?
- What is the probability of pulling any one specific number from the bag?
- If Marissa flipped heads 40% of the time when pulling a 3, how many times did that occur?
- If she repeated the experiment with 100 trials, how many times would she expect to pull 2 and flip tails?
- What is the probability of pulling a 4 and flipping tails if we assume fair conditions?
Tip: To find percentages of a total, always multiply the percentage (as a decimal) by the total count!
