Question

Dan rolls 2 fair dice and adds the results from each.
Work out the probability of getting a total of 3.

Answer 1

Answer: 2

Step-by-step explanation:

1+2, 2+1

Therefore, the probability of getting a total of three is 2

Answer 2

Probability of getting total of three when two fair dice rolled is equals to $\frac{1}{18}$ .

What is probability?

" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Probability $= \frac{Number of favourable outcomes}{Total number of outcomes}$

According to the question,

Dan rolls two fair dice,

Possible outcomes are $= \{ (1,1), (1,2), (1,3) , (1,4). .........., ( 6,5), (6,6)\}$

Total number of outcomes $= 36$

Condition given,

Favourable outcomes for total of $3$ $= \{(1,2) , (2,1)\}$

Substitute the value in the formula of probability we get,

Probability of getting $3$

$= \frac{2}{36}\\\\= \frac{1}{18}$

Hence, probability of getting total of three when two fair dice rolled is equals to $\frac{1}{18}$ .
