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 ive been stuck on this for a long time
Tomtit [17]

Answer:

Below

Step-by-step explanation:

You can use Pythagorean theorem to find the hypotenuse of a right triangle.

a2 + b2 = c2

The square root of 15 = 3.8729.... (a bunch of other numbers)

4^2 + 3.8729^2 = c2

16 + 15 = 31

Now that you have this, you need to find the square root

The square root of 31 = 5.56775436

Rounding this to the tenth it would be: 5.57

Final answer: C = 5.57

hope this helps! :)
