Steve makes the tree diagram shown to find the possible outcomes of tossing a penny, a nickel, and a dime. what is the probability that all three coins land on the same side?

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!
