Rachel has 10 sweets in a bag. 7 of the sweets are yellow.
3 of the sweets are red.
Rachel takes random sweets from the bag, one at a time, until she gets a red sweet.
She does not replace the sweets that she takes from the bag.
Rachel stops as soon as she gets a red sweet.
Work out the probability that Rachel takes no more than three sweets from the bag.

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 %

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":
