Q. |
Two dice are thrown simultaneously. Find the probability of getting a multiple of 2 on one dice and multiple of 3 on the other dice. |

✖ A. |
5/12 |

✔ B. |
11/36 |

✖ C. |
5/36 |

✖ D. |
13/36 |

**Solution:**

Option(**B**) is correct

Let $X$ be required events and $S$ be the sample space,

then $X$ ={(2,3),(2,6),(4,3),(4,6),(6,3),(6,6),(3,2),(6,2),(3,4),(6,4),(3,6)}

$n(X)=11$, $n(S)=36$

Hence, required probability

\(=\dfrac{n(X)}{n(S)}\)

\(=\dfrac{11}{36}\)

why can't we take (2,1)

Since second dice contains multiple of 3 only. In your case it is 1, which is not a multiple of 3.

There are 11 favourable cases as (6,6) will be repeated.
