Question

40% of OatyPop cereal boxes contain a prize. Hanna plans to keep buying cereal until she gets a prize. What is the probability that Hannah only has to buy 3 or less boxes before getting a prize? If we use a random number generator ranging from 1-10 and assign 1-4 as the prize and 5-10 as no prize, what is the BEST way to perform the simulation?  a. keep track of how many times you see a 1,2,3 or 4 in 150 tries. These will represent the number of prizes you get in all.  b. keep track of how many tries it takes before you see a 1,2,3 or 4. These represent the number of purchases it will take to get a prize. Repeat this 150 times.  c. keep track of how many tries it takes before you see a 1,2,3 or 4. These represent the number of purchases it will take to get a prize. Repeat this 3 times.

Answer 1

Answer:

keep track of how many tries it takes before you see a 1,2,3 or 4. These represent the number of purchases it will take to get a prize. Repeat this 150 times, option b

Answer 2

The correct answer is A that Keeps track of how many tries it takes before you see a 1,2,3, or 4. These represent the number of purchases it will take to get a prize. Repeat this 150 times.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of several favorable outcomes to the total number of outcomes.

Number of OatyPop cereal boxes That contains a prize = 40 %

Number of OatyPop cereal boxes Which does not contain a prize

= 100% - 40 % = 60%

Probability that Hannah only has to buy 3 or less boxes before getting a prize  =  40 %+ 60 %×  40 % +  60 % × 60 % × 40 %

= 0.40 +0.24 + 0.144

= 0.788

If we use a random number generator ranging from 1-10 and assign 1-4 as the prize and 5-10 as no prize, the best way to perform the simulation

Option(A) is the correct answer that Keeps track of how many tries it takes before you see a 1,2,3, or 4. These represent the number of purchases it will take to get a prize. Repeat this 150 times.
