Answer with explanation:

An experiment is said to be binomial, if it has n number of trials,and out of n trials,when each trial is performed Independently, there are only two possible outcomes,one Success and other will be failure.

In option A,

Number of trials = 24,which is fixed.

Success= getting 4,when a die is rolled.

Failure = Getting ,number other than,4 , that is , 1,2,3,5,6.

So, This is Binomial Experiment.

In Option B,

Number of trials is not fixed.So, This is not Binomial Experiment.

In Option C

Number of trials is not fixed.So, This is not Binomial Experiment.

In Option D

Number of trials = 24

But, there are more than two possible outcomes.So,this is not a Binomial Experiment.

Option A: is a Binomial Experiment.

Rolling a six-sided number cube 24 times and recording if a 4 comes up.

Answer from: aronandalp3yep6

A binomial experiment satisfies four conditions. It should have four number of trials. Each trial should be independent of the other trials. Outcomes should only be two. Finally, the probability of both outcome should be constant for each trial. I think the correct answer is C, Rolling a six-sided number cube and recording the number until an even number comes up.

Answer from: Quest

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

Answer from: Quest

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 %
