Events A and B are disjointed. P(A) = 4/11; P(B) = 3/11, P(A and B)= 2/11 . Find P(A or B).
Anettt [7]

Answer:

P(A\:or\:B)=\frac{7}{11}

Step-by-step explanation:

If the two events are disjoint, then P(A or B)=P(A)+P(B).

We were given that:

P(A)=\frac{4}{11}

and

P(B)=\frac{3}{11}

This implies that:

P(A\:or\:B)=\frac{4}{11}+\frac{3}{11}

We simplify the right hand side to obtain:

P(A\:or\:B)=\frac{4+3}{11}

P(A\:or\:B)=\frac{7}{11}
