You are rolling the pair of dice over and over until the minimum of the two dice is greater than or equal to 5. what is the expected number of times you must roll the pair of dice before you stop?

9

Step-by-step explanation:

we are rolling two die until we get minimum of 5 in two die

we get (5,5) (5,6) (6,5) (6,6)

total number of sample space =36 as two die is rolled

so the probability of the event

so

where x=1,2,3,4--------------

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
