Consider the trial on which a 3 is first observed in successive rolls of a six-sided die. Let A be the event that 3 is observed

Gwar [14]

Answer:

1) 0.1667

2) 0.8333

3) 1

Step-by-step explanation:

Let A be the event that 3 is observed on the first trial.

Let B be the event that at least two trials are required to observe a 3

a) A six-sided die has 6 possible outcomes of 1,2,3,4,5,6

3 is one of the six possible outcomes

P(A) = no of favourable outcomes /no of possible outcomes

P(A) = 1/6 = 0.1667

b) The event of requiring at least two trials to observe a 3 is the event of not observing a 3 on the first trial.

P(B) = P(A')

P(A')= 1 - P(A)

P(B) = 1 - 1/6

= 5/6 = 0.8333

c) P(AnB) = P(A) + P(B)

= 1/6 + 5/6

= 6/6 = 1

Complete the point-slope equation of the line through (3,6)(3,6)left parenthesis, 3, comma, 6, right parenthesis and (5,-8)(5,−8

ArbitrLikvidat [17]

Answer:

The required equation of line in point-slope form is:

$y-6 = -7(x-3)$

Step-by-step explanation:

Given points are:

(x1,y1) = (3,6)

(x2,y2) = (5,-8)

The point-slope form of an equation is given by:

$y-y_1 = m(x-x_1)$

Here m is slope of the line and (x1,y1) is a point on line

The slope is calculated using the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Putting the values we get

$m = \frac{-8-6}{5-3}\\m=\frac{-14}{2}\\m= -7$

Putting in the equation

$y-y_1 = -7(x-x_1)$

Now we have to put a point in the equation, putting (3,6) in the equation

$y-6 = -7(x-3)$

Hence,

The required equation of line in point-slope form is:

$y-6 = -7(x-3)$
