The probability shows that the total number of times it'll land on 1 or 5 will be 78.
<h3>How to calculate the probability?</h3>
The number of times that 1 will be rolled will be:
= 0.1 × 300
= 30
The number of times that 5 will be rolled will be:
= 0.16 × 300
= 48
Therefore, the total number of times it'll land on 1 or 5 will be:
= 30 + 48
= 78

To find the answer to this problem, you just need to figure out which total amount of candy is divisible by 7.
161/7=23
<span>162/7=23.1428571429
</span>145/7=<span>20.7142857143
128/7=</span><span>18.2857142857
Obviously, Julie cannot give a fraction of an amount of candy to someone. So that rules out that she had 162, 145, or 128 pieces of candy.
The only amount of candies that Julie could have that is divisible by 7 is 161 candies, which means that 161 is your answer.</span>
