Please help me with this

Step-by-step explanation:

sum of ∠QPR and ∠RPS is 180 as ∠QPS is a straight line

6x + 11 + 7x + 143 = 180   {add like terms}

13x + 154 =180

13x = 180 - 154

13x = 26

x = 26/13

x = 2

∠RPS = 6x + 11 = 6*2 +11 = 12 + 11 = 23°

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 %
