Given that P(E) = 0.38, P(F) = 0.38, and P(E ∩ F) = 0.12. Find P(E ∪ F, how do I work this out?
natulia [17]

Answer: The value of P(E∪F) = 0.64.

Step-by-step explanation:

Since we have given that

P(E) = 0.38

P(F) = 0.38

P(E∩F) = 0.12

So, we need to find the P(E∪F).

As we know the formula for the sets.

P(E\cup F)=P(E)+P(F)-P(E\cap F)\\\\P(E\cup F)=0.38+0.38-0.12=0.64\\\\P(E\cup F)=0.64

Hence,the value of P(E∪F) = 0.64.

Lera25 [3.4K]
The ladder forms the hypotenuse of a right triangle. Solve for a 

<span>a^2 + b^2 = c^2 </span>
<span>a^2 + 9^2 = 18^2 </span>
<span>a^2 + 81 = 324 </span>
<span>a^2 = 243 </span>
<span>a = 15.589 = 15.6 feet</span>

The equation below describes a parabola. If a is positive, which way does the parabola open?
madreJ [45]

we know that

the equation

y=ax^{2}

describe a vertical parabola with vertex at point (0,0)

if  a> 0 -------> the parabola open Up and the vertex is a minimum

if  a< 0 -------> the parabola open Down and the vertex is a maximum

in this problem we have

a> 0 ---> because is positive (given problem)

so

The vertex is a minimum

therefore

<u>the answer is the option C</u>

Up
