Sets A and B are independent events and are mutually exclusive

Lynna [10]

The solutions are ${P}({A} \text { and }B})=0$ and $P}({A} \text { or } {B})=\frac{7}{12}$

Explanation:

Given that the sets A and B are independent events and are mutually exclusive events.

We need to determine the value of $P(A \text { and } B)$ and $P(A \text { or } B)$

The value of $P(A \text { and } B)$ :

Since, the sets A and B are mutually exclusive events, it is impossible for the two events to occur together.

Hence, we have,

${P}({A} \text { and }B})=0$

Thus, the value of $P(A \text { and } B)$ is 0.

The value of $P(A \text { or } B)$ :

For mutually exclusive events, the value of $P(A \text { or } B)$ is given by the formula,

$P(A \text { or } B)=P(A)+P(B)$

Substituting the values, we get,

$P(A \text { or } B)=\frac{1}{4}+\frac{1}{3}$

$P}({A} \text { or } {B})=\frac{7}{12}$

Hence, the value of $P(A \text { or } B)$ is $\frac{7}{12}$

Thus, the solutions are ${P}({A} \text { and }B})=0$ and $P}({A} \text { or } {B})=\frac{7}{12}$

(50 POINTS!!) The two triangles are similar. What is the value of x?

Kamila [148]

Place (3x + 1)/12, and (4x)/15 (Note: the bottom triangle's base is 12 + 3)

Set the two equal to each other

(3x + 1)/12 = (4x)/15

Cross multiply

15(3x +1)/12(12) = 12(4x)/15(15)

15(3x + 1) = 12(4x)

Distribute the 15 to the two terms in the parenthesis, and 12 to 4x

15(3x) = 45x
15(1) = 15
12(4x) = 48x

45x + 15 = 48x

Isolate the variable, subtract 45x from both sides

45x (-45x) + 15 = 48x (-45x)

15 = 48x - 45x

Simplify

15 = 3x

Isolate the x, divide 3 from both sides

15/3 = 3x/3

x = 15/3

x = 5

5 is your answer

hope this helps
