Let p(z)=0.54, p(y)=0.22, and p(z u y)= 0.62. Find each probability.
Marysya12 [62]

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

What is the slope of (15,9), (-14,-9)
Lady bird [3.3K]
The formula for slope:

m = \frac{y_{2} - y_1 }{x_2-x_1}

\frac{-9-9}{-14-15}

-9-9 = -18
-14-15 = -29

\frac{-18}{-29}
