P(A) = 0.40 P(B) = 0.50
P(A and B) = 0.10
What is P(BIA)?
A. 0.25
B. 0.10
C. 0.50
O D. 0.20

Correct option is

A 0.39

Step-by-step explanation:

P(A∪B)=P(A)+P(B)−P(A∩B)

⇒P(A∪B)=0.25+0.50−0.14=0.61

P(neither A nor B)=P(

Option A is correct.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
