E and F are mutually exclusive events. P(E)=0.3; P(F) =0.2. Find P(E | F)

0

Step-by-step explanation:

P(E|F) = P(E and F)/P(F) = 0/0.2

Events that are mutually exclusive exclude each other.  That means if one

occurs, the other is excluded.  That means if one occurs, the other cannot

occur.

So that tells us that the probability of them both happening is impossible,

which mean P(E and F) = 0

the answer is c 150

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
