Steve makes the tree diagram shown to find the possible outcomes of tossing a penny, a nickel, and a dime. What is the probabili ty that ALL three coins land on the same side?
1 answer:
Hi there! Since there is a 50% chance of any coin landing on heads and a 50% chance of any coin landing on tails, the chance that all 3 coins land on either heads or tails (the same side) is 50% * 50% * 50%. 50% * 50% * 50% = 0.5 * 0.5 * 0.5 = 0.25 * 0.5 = 0.125 Now, we need to convert into a percentage: 0.125 = 12.5% So, the answer is 12.5%. Hope this helps!
