Two events are disjointed. find p(a or b), if p(a) = 1/7
and p(b) = 3/7.
1/7
3/7
4/7
2/7

4/7

Step-by-step explanation:

P(A or B) when A and B are disjointed is P(A)+P(B)

P(A or B)=P(A)+P(B)

P(A or B)=1/7 +3/7

P(A or B)=4/7

450 is the final answer! : )

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
