we have
p (a) =2/5 p(b)=1/4 ( a and b=1/25
Remember that
we know that for two independent events A,B.
⇒ P(A∩B)=P(A)*P(B)
we have
P(A)=2/5 and P(B)=1/4
so
P(A∩B)=(2/5)*(1/4)=2/20=1/10
that means
<h2>events are dependent</h2>
Answer: B. 1/2(y - 116) = 64
Step-by-step explanation:
Since, we know that,
The angle formed by two tangent =
= 
Here, Major arc = y°
Minor arc = 116°
And, Angle made by two tangents YX and YZ,

( because,
)
⇒ 
Which is the required equation to find y, the measure of XWZ.
Thus, Option B is correct.
