0.58

Justification:

<u>As we know that</u>,

P(E) + P(Ē) = 1.
0.42 + P(Ē) = 1
P(Ē) = 1 - 0.42
P(Ē) = 0.58

<u>Hence, the probability of non occuring event is 0.58</u>

z=2

Further explanation:

When two triangles are congruent, then their respective sides will also be congruent or equal

As it is given that

ΔABC≅ΔDFE

Which means that

EF = BC

ED=AC

FD=AB

Now,

$EF=BC\\Putting\ the\ values\\x+15=2x+5\\x-2x=5-15\\-x=-10\\x=10\\AND\\FD=AB\\Putting\ the\ values\\4y=8y-20\\4y-8y=-20\\-4y=-20\\\frac{-4y}{-4}=\frac{-20}{-4}\\y=5\\AND\\ED=AC\\10z-5=3z+9\\10z-3z=9+5\\7z=14\\\frac{7z}{7}=\frac{14}{7}\\z=2$

Hence, the values of x, y and z are as follows:

x=10

y=5

z=2
