What is the probability of rolling a dice at most 3 times until a 6 occurs
IRISSAK [1]

Answer:

Probablity of getting six in at most three roll= 0.199.

Step-by-step explanation:

Given: Dice rolled at most 3 times untill a 6 occurs.

First, finding the probablity of getting 6 in a dice if rolled once.

Probablity= \frac{chances\ of\ occurance}{Total\ number\ of\ event}

We know, dice have six side, therefore, total number of event will be 6.

∴ Probablity of getting six in one roll= \frac{1}{6}

As given, Dice is rolled at most 3 times.

Now, finding the probablity of getting 6 in a dice if rolled 3 times.

∴ Probablity of getting six in three roll= \frac{1}{6}+(\frac{1}{6})^{2} +(\frac{1}{6})^{3}

⇒ Probablity of getting six in three roll=  \frac{1}{6}+\frac{1}{36} +\frac{1}{216}

Taking LCD 216

⇒Probablity of getting six in three roll= \frac{1\times 36+ 6\times 1+1}{216}

⇒Probablity of getting six in three roll= \frac{43}{216}

∴Probablity of getting six in three roll=0.199

Please ' help me I need it please I'm begging you
vazorg [7]

Answer: 0.75 (choice B)

=============================================

Explanation:

One way to set up the equation is to think of it like this

vertical/horizontal = vertical/horizontal

So we could say

(3.5)/(28) = x/6

Cross multiply and solve for x

3.5*6 = 28*x

21 = 28x

x = 21/28

x = (3*7)/(4*7)

x = 3/4 in fraction form

x = 0.75 in decimal form

-------------

Another possible set up equation is

28/6 = (3.5)/x

in this case I divided the horizontal sides together (28 and 6) and the vertical sides divide to form their own separate fraction as well.

Solving that equation should lead you to x = 3/4 = 0.75

Other equations are possible.

What is the midpoint (-13,4) and (0,9)
Nadusha1986 [10]
A point serves as the midpoint<span> of a segment if it lies on the segment and it divides the segment into two congruent segments. Other notes to. So the coordinates of B and D are </span>4<span> and 10, respectively,. and the. Because AC = </span>9<span> and CE = </span>9<span> so C divides into two. 10 + 3 = </span>13<span>, so the coordinate </span>for<span> the other endpoint is </span>13<span>.
