Answer:
[tex]P(A\:or\:B)=\frac{7}{11}[/tex]
Step-by-step explanation:
If the two events are disjoint, then P(A or B)=P(A)+P(B).
We were given that:
[tex]P(A)=\frac{4}{11}[/tex]
and
[tex]P(B)=\frac{3}{11}[/tex]
This implies that:
[tex]P(A\:or\:B)=\frac{4}{11}+\frac{3}{11}[/tex]
We simplify the right hand side to obtain:
[tex]P(A\:or\:B)=\frac{4+3}{11}[/tex]
[tex]P(A\:or\:B)=\frac{7}{11}[/tex]
Answer:
5/11
How I got my answer:
For overlapping events, you would subtract P(A and B) from the sum of P(A) and P(B).
In this case, you would do 4/11 + 3/11, which equals 7/11 minus 2/11, which equals 5/11.
