E and F are mutually exclusive events. P(E)=0.3; P(F) =0.2. Find P(E | F)
Arada [10]

Answer:

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

Given that the volume of a certain cube is 125 cubic inches, find the dimensions given below
AURORKA [14]
If cube volume = 125, length of 1 side = cube root of 125 =5 inches
Surface area of a cube = surface area of each face * 6
each face is 5 inches by 5 inches = 25 square inches per face.
TOTAL AREA = 25 * 6 = 150 square inches

Choose three intervals on the real number line that contain both rational and irrational numbers. Do you think that any given in
Helen [10]

Any real number line ranges from negative infinity to positive infinity. A real number number line consists of all the rational and irrational numbers. Let us take three intervals which contain both the rational and irrational numbers.

First interval:  [3,4]

Since every integer is a rational number, 3 and 4 are both rational. In this interval there occurs the value of π (3.14159..) which is an irrational number.

Second interval :  [0,2]

0 and 2 are integers and hence are rational. In this interval, occurs √2 (1.41421...) is an irrational number.

Third interval : [2,3]

In this interval, Eulers number 'e' lie whose value is (2.718281.. )

Hence we can conclude that, there occurs an irrational number between any two rational number.
