Answer:

i.  P(A) = \frac{1}{10}

ii.  P(B) = \frac{1}{10}

iii.   P(A) = \frac{3}{5}

iv.   P(B) = \frac{2}{5}

Step-by-step explanation:

Given

Time: 07 2(A) 5(B)

Calculating (a)

First, we need to list out the possible sample space, S of A

S = \{0,1,2,3,....,9\}

n(S) = 10

Probability of A being a 4 is the number of occurrence of 4 divided by the number of sample space

A = \{4\}

n(A) = 1

Hence;

P(A) = \frac{n(A)}{n(S)}

P(A) = \frac{1}{10}

Calculating (b)

First, we need to list out the possible sample space, S of B

S = \{0,1,2,3,....,9\}

n(S) = 10

Probability of B being a 8 is the number of occurrence of 8 divided by the number of sample space

B = \{8\}

n(B) = 1

Hence;

P(B) = \frac{n(B)}{n(S)}

P(B) = \frac{1}{10}

Calculating (c)

Using the sample space in (a)

n(S) = 10

Probability of A being less than 6 is the number of occurrence of less than 6 divided by the number of sample space

A = \{0,1,2,3,4,5\}

n(A) = 6

Hence;

P(A) = \frac{n(A)}{n(S)}

P(A) = \frac{6}{10}

P(A) = \frac{3}{5}

Calculating (d)

Using the sample space in (b)

n(S) = 10

Probability of B being greater than 5 is the number of occurrence of greater than 5 divided by the number of sample space

B = \{6,7,8,9\}

n(B) = 4

Hence;

P(B) = \frac{n(B)}{n(S)}

P(B) = \frac{4}{10}

P(B) = \frac{2}{5}

What value of x makes the equation true <br> 2 (6x-1) = -38
Anestetic [448]

Answer:

<h3>\boxed{\bold{\boxed{ \sf{x =  - 3}}}}</h3>

Step-by-step explanation:

\sf{2(6x - 1) =  - 38}

Distribute 2 through the parentheses

⇒\sf{12x - 2 =  - 38}

Move constant to right hand side and change it's sign

⇒\sf{12x =  - 38 + 2}

Calculate

⇒\sf{12x =  - 36}

Divide both sides of the equation by 12

⇒\sf{ \frac{12x}{12}  =  \frac{ - 36}{12} }

Calculate

⇒\sf{x =  - 3}

Hope I helped!

Best regards!!
