Step 1: The probability of any event can be defined as:
[tex]\text{Probability of any event = }\frac{N\text{umber of required outcomes}}{N\text{umber of total possible outcomes}}[/tex]Step 2:
Look at the word LOLLIPOP and the word HALLOWEEN
Number of total possible outcomes = 8
Number of required outcomes = 5
(Because L and O are the only letters in the word HALLOWEEN)
Step 3:
[tex]\begin{gathered} \text{Therefore,} \\ \text{Probability that the letter pick from LOLLIPOP is a letter in HALLOWEEN } \\ =\frac{5}{8}\text{ } \end{gathered}[/tex]Step 4: Final answer
= 5/8
