Answer» Red is the correct answer Ambitious→Number of different colour clips in the bag = 30 red + 25 blue + 25 black + 20 green → Also, it is given that you will get Rs 21 per clip , if my colour comes out. As i want maximum amount of money , so i will select that clip which is highest in number, which is red clip being 30 in number. total number of clips are 100➡️probability of picking a red clip is 30/100=3/10➡️probability of picking a blue clip is 25/100=1/4➡️probability of picking a black clip is 25/100=1/4➡️probability of picking green clip is 20/100=1/5 so probability of red clip is maximum so I pick red clip Plz like my answer and accepted as best plz i will select that colour which has greater probability of outcome! here total number of ball is 100 probability of red =3/10 probability of blue and black =1/4 each probability of black =1/5 i will choose red coloured brush green is the right answer red is correct answer of your question The answer for the question is red ball 30 because the probability of coming red is more than others red color i select to make money red is the correct answer of the given question red color i will select to make money Red is correct answer red is the answer of the following |
