Answer 1

Answer:

the probability is 1/6th hope it helps

Answer 2

In a game a dice is rolled over 3 times and the number that appears on top face is noted what is probability​ of getting at least one?

The probability of getting at least one is  $\frac{91}{216}$ .

Given:

A dice is rolled over 3 times

To Find:

The probability of getting at least one

Solution:

Probability of getting a one in each dice =1/6

Probability of not getting a one in each dice=5/6

Probability of getting at least one,when a dice is rolled thrice

= 1-Probability of not getting a one each time

=$1-\frac{5}{6} *\frac{5}{6}*\frac{5}{6}\\\\1-\frac{125}{216} \\\\\frac{216-125}{216} \\\\\frac{91}{216}$

Therefore,the probability of getting at least one is $\frac{91}{216}$.
