1. you roll two number cubes. find the probability that the sum of the cubes is 5 or less. write as a decimal and round to 3 decimal places, or write as a percentage and round to one decimal place.

2. you roll two number cubes. find the probability of the sum of the cubes being prime. write as a decimal and round to 3 decimal places, or write as a percentage and round to one decimal place.

1 is 27.8%

2 is 41.7%

Step-by-step explanation:

To calculate 1 there is a 10/36 chance (2, 3, 4, 5 out of possible roles of 2 - 12)

To calculate 2 there is a 15/36 chance (2, 3, 5, 7, 11 are prime)

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
