Answer: more protons are present in the atomic nucleus
Answer:5/6
Explanation:
Each Coin has two possible outcomes heads or tails
if there are 3 coins and two outcomes for each coin you multiply 3 and 2 and that is a total of 6 possible outcomes
Since the question is saying it can't have more than 2 heads we subtract what we don't want with the total possible outcomes
Out of the 6 outcomes how many are there where all of the coins land on heads? Only 1
6-1=5
Out of 6 outcomes 5 of them the coins landed on 2 heads or less
5/6
