"Tossing a die" is assumed to mean choosing a random face of a cube with faces numbered 1 through 6 such that the probability of choosing any particular face (number) is 1/6.

Event <em>a</em> is "observe a 2". Event <em>b</em> is "observe an even number". The event "<em>a</em> and <em>b</em>" is "observe 2 and an even number". This matches precisely the description for event <em>a</em>. In other words

... <em>a</em> and <em>b</em> = <em>a</em>

... p(<em>a</em> and <em>b</em>) = p(<em>a</em>) = p(choosing 2) = 1/6

Answer:

<u>Option-</u> B

  • An experiment involves tossing a die. these are some of the events during which we can be able to observe an even number.                                                                                                                      

Step-by-step explanation:

  • It is more obviously to know that there will be six sides for us to observe and each time we will get an even number to observe during the process.So, it all goes with the mechanisms of the probability that are taken under considerations when we speak about such events to happen.

If a sponsored link was delivered 100 times and 10 people clicked on it, then the number of impressions is 100, the number of cl
Rudik [331]

Answer:

Option A.

Step-by-step explanation:

It is given that a sponsored link was delivered 100 times and 10 people clicked on it.

Number of impressions = 100

Number of clicks = 10

The formula for click-through-rate (CTR) is

CTC=\dfrac{\text{Total measured clicks}}{\text{Total measured impression}}\times 100

CTC=\dfrac{10}{100}\times 100

CTC=10

The click-through-rate (CTR) would be 10%. Therefore, the correct option is A.

How do you estimate 52% of 84?
Nastasia [14]
The way to answer this question is to first make 52% into a decimal:

52% = 0.52

so now we will simply multiply:

   84
x.52

once you have multiplied these numbers it comes out to be 43.68.
So your answer is 43.68.

A triangle is graphed in the coordinate plane. The vertices of the triangle have coordinates (–3, 1), (1, 1), and (1, –2). What
vladimir2022 [97]

Answer:

The perimeter of the triangle is 12\ units

Step-by-step explanation:

Let

A(-3,1),B(1,1),C(1,-2)

we know that

The perimeter of triangle is equal to

P=AB+BC+AC

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

step 1

Find the distance AB

A(-3,1),B(1,1)

substitute in the formula

AB=\sqrt{(1-1)^{2}+(1+3)^{2}}

AB=\sqrt{(0)^{2}+(4)^{2}}

AB=4\ units

step 2

Find the distance BC

B(1,1),C(1,-2)

substitute in the formula

BC=\sqrt{(-2-1)^{2}+(1-1)^{2}}

BC=\sqrt{(-3)^{2}+(0)^{2}}

BC=3\ units

step 3

Find the distance AC

A(-3,1),C(1,-2)

substitute in the formula

AC=\sqrt{(-2-1)^{2}+(1+3)^{2}}

AC=\sqrt{(-3)^{2}+(4)^{2}}

AC=5\ units

step 4

Find the perimeter

P=AB+BC+AC

substitute the values

P=4+3+5=12\ units
