Question

What is the probability of getting 3 or 4 in 3 consecutive rolls of a dice?

Answer 1

Answer:

2/6*2/6*2/6

1/27

Step-by-step explanation:

so the possible list of answers is{1,2,3,4,5,6}  i.e. 6 total possibilities

but we only need {3,4} i.e. 2 values

the probability for first roll is 2\6

for 2 rolls is 2\6*2\6

and for 3 rolls 2\6*2\6*2\6

Answer 2

The probability of getting 3 or 4 when a dice is rolled 3 times is 1/27.

Probability

Probability is a branch of mathematics that studies the probability of a random event occurring. When a coin is tossed into the air, for example, the possible outcomes are Head and Tail.

Formula to find probability

Probability=possible outcomes/total outcomes Probability

given:

A dice is rolled 3 times.

Solution for the probability when dice is rolled thrice

Total numbers of outcomes when a dice is rolled once  =6

ie $S = {1,2,3,4,5,6}$

so the possible outcomes =2

ie 3, 4

when a dice is rolled once probability of getting 3 or 4 =possible outcomes/total outcomes Probability

=$2/6=1/3$

now,

when the dice is rolled thrice:

The probability of getting $3 or 4= 1/3*1/3*1/3$

$=1/27$

Hence the probability of getting 3 or 4 when dice is rolled three times is =1/27
