Answer:
1/6
Explanation:
The total number of months in a year = 12
[tex]\begin{gathered} P(\text{July)}=\frac{1}{12} \\ P(\text{October)}=\frac{1}{12} \end{gathered}[/tex]Therefore, the probability that it will be July or October:
[tex]\begin{gathered} P(\text{July or October)=}P(\text{July)}+P(\text{October)} \\ =\frac{1}{12}+\frac{1}{12} \\ =\frac{2}{12} \\ =\frac{1}{6} \end{gathered}[/tex]The required probability is 1/6.
Note:
• Use addition for OR
