Answer : p(only z)=0.40 and p(only u)=0.08
Explanation :
We have given that ,
p(u)=0.22,
p(z∪u)=0.62,
p(z)=0.54
By using probability rule of union of 2 events, we have,
p(z)+p(u)-p(z∩u)=p(z∪u)
⇒0.54+0.22-p(z∩u)=0.62
⇒0.76-p(z∩u)=0.62
⇒(-)p(z∩u)=0.62-0.76
⇒(-)p(z∩u)= (-)0.14
⇒p(z∩u)=0.14
Now,
p(only z)=p(z)-p(z∩u)
=0.54-0.14
=0.40
and,
p(only u)=p(u)-p(z∩u)
=0.22-0.14
=0.08
∴ Each probability will be
p(only z)=0.40
p(only u)=0.08
Answer:
The second equation can be used
Step-by-step explanation:
Just plug in the values and the equation should look like this 8^2 + b^2 = 12^2
12 is the hypotenuse to plug that into c
and 8 is just a leg so you can either put it in a or b
18. 105=2x-11 so 105+105=210 and all four angels equal 360 so 360-210=150 so 150/2=75
19. 6x+19+x =180
X=23
So AEB:75 BEC:123 CED:75 AED:23
