Events a, b, and c in a sample space have p(a)=0.2, p(b)=0.4, and p(c)=0.1. find p(a ∪ b ∪

Julli [10]

If $A$ and $B$ are mutually independent, then $\mathbb P(A\cup B)=\mathbb P(A)+\mathbb P(B)$ and $\mathbb P(A\cap B)=0$ .

If $A$ and $C$ are independent, then $\mathbb P(A\cap C)=\mathbb P(A)\cdot\mathbb P(C)$ . Ditto for $B$ and $C$ .

The inclusion/exclusion principle says that

$\mathbb P(A\cup B\cup C)=\mathbb P(A)+\mathbb P(B)+\mathbb P(C)-\mathbb P(A\cap B)-\mathbb P(A\cap C)-\mathbb P(B\cap C)+\mathbb P(A\cap B\cap C)$

Since $A$ and $B$ are mutually exclusive, their intersection is the empty set. It then follows that $A\cap B\cap C$ also is the empty set, so the last probability is also 0.

Plug in what we know:

$\mathbb P(A\cup B\cup C)=0.2+0.4+0.1-0-0.2\cdot0.1-0.4\cdot0.1+0$

$\implies\mathbb P(A\cup B\cup C)=0.64$

Dafna1 [17]

Answer:

$\frac{10}{11}$

Step-by-step explanation:

The formula for the trigonometric function sin is:

$sin$ Ф $=\frac{opposite}{hypotenuse}$

The side opposite to the ∠g is x, which is equal to 10

$opposite=x$ $x=10$

the hypotenuse of the triangle is z, which is equal to 11

$hypotenuse=z$ $z=11$

so the ratio is:

$\frac{10}{11}$

Y = –3x + 5 y = mx + b Which values of m and b will create a system of linear equations with no solution? m = –3 and b = –3 m =

beks73 [17]

Answer:

(A) m = –3 and b = –3

Step-by-step explanation:

If m=–3 and b=–3

The system of linear equations:

y = –3x + 5

y = mx + b

Becomes

y = –3x + 5 ......(i)

y = –3x – 3 .......(ii)

Notice that 5 is added to -3x in (i) and -3 is added to -3x in (ii) and both equals y. This is impossible. Thus the system has no solution.
