In a simultaneous throw of two dice what is the probability of getting a doublet

AcademicMathematicsNCERTClass 10

Given:

Two dice are thrown simultaneously. 

To do:

We have to find the probability of getting a doublet.

Solution:

When two dice are thrown, the total possible outcomes are $6\times6=36$.

This implies,

The total number of possible outcomes $n=36$

Outcomes where we get a doublet are $[( 1,\ 1),\ ( 2,\ 2),\ ( 3,\ 3),\ ( 4,\ 4),\ ( 5,\ 5),\ ( 6,\ 6)]$

Total number of favourable outcomes $=6$

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

Therefore,

Probability of getting a doublet $=\frac{6}{36}$

$=\frac{1}{6}$

The probability of getting a doublet is $\frac{1}{6}$.

Answer: Option 1

In a simultaneous throw of dice, n (S) = (6 × 6) = 36 Let E = event of getting a doublet = [(1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)] ∴ P(E) = $$\frac{{n (E)}}{{n (S)}}$$ = $$\frac{{6}}{{36}}$$ = $$\frac{{1}}{{6}}$$
