Peter throws two different dice together and finds the product of the two numbers obtained. Rina throws a die and squares the number obtained.

Who has the better chance to get the number 25.

Answer:

Total possible events in case of peter is 36 favourable outcome is (5, 5)

So                                            \[n(E)=1\]

So                P (getting 25 as product)\[=\frac{1}{36}\]

While total possible event in case of Rina is 6

Favourable outcome is 5

\[n(E)=1\]

So        P (square is 25)\[=\frac{1}{6}\]

As \[\frac{1}{6}>\frac{1}{36}\], so Rina has better chance.
