Answer 1

Rina has better chance than Peter

Step-by-step explanation:

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

To get 25 as product of two numbers on dice

dice has number 1 to 6

only option is to have 5 , 5 on each dice

So only favorable combination = 1

Total combination = 6 * 6 = 36

Probability of getting product 25 = 1/36

Rina to get 25 as square of number

5² = 25

so favorable outcome to get number 5 on dice = 1

Total out come = 6

Probability of getting square as 25 = 1/6

1/6 > 1/36

so Rina has better chance than Peter
