00:00Okay, so dear students, in this question, we are given a box contain 3 blue, 2 white and 4 red marble.
00:09So we have a box. This is our box.
00:11This is our box.
00:14And box ke an der kya hai?
00:15Blue marble.
00:17Kisina hai?
00:183 blue.
00:202 white.
00:222 kya hai?
00:22White.
00:26Marble hai.
00:26And 4 kya hai?
00:284 number ke red marble hai.
00:324 red marble hai.
00:34If a marble is drawn at random from the box, what is the probability that it will be?
00:40Tha fahle toh probability ke division hai.
00:43Hamaarai paas toh equation hai.
00:44Woh equation kya hai?
00:45Dekho.
00:45Hamaarai paas toh equation hai na?
00:47Woh equation me hai hai.
00:49Shafi shafi shafi.
00:50Ye hai humara equation.
00:51Equation kya hai?
00:52Equation hai?
00:55Number of outcome favorable to e.
00:58Divide by number of possible outcome of the experiment.
01:01Ok.
01:02So yehi hai humara.
01:03So ye question ka.
01:05Pahle yeh likhengi hai.
01:06Uskye baar yeh likhengi hai.
01:08Total kytne hai?
01:09Number of all possible outcome.
01:12Yarni ki,
01:13Anadar se kitnye ball nikal saktte hai?
01:15Pahit kitne nikal saktte hai?
01:153, 2, 5, 4, 9, 9, total, total ball, this is our total outcome, total possible outcome,
01:279, now what is the idea, first, P of, this is the event E, let the event E be the white ball,
01:36this is the event F, let the event F be the blue ball, and third, G, let the,
01:44event G be the red ball, so P of E kya hooga, so number of ball, white ball, number of white ball kitnay hai, 2,
01:54divide by total number of ball kitnay hai, 9, hai na, so yeh aap ka answer ha gya, 1 by 9, now second, P of F,
02:04P of F kya hai, blue ball, so total number of blue ball, 3, 3 divide by 9, 3 is a 9, yeh answer ho gya,
02:131 by 3, kitna ho gya, 1 by 3, ab kya hai, red, so red kitnay hai, what is 4, so P of G kya hai,
02:21probability of getting red ball, is P of G se dikha hai hai, so yeh kitnay ho gya, 4 by 9, 4 divide by 9,
02:30gya hai, ius ka kuch nahi ho saken, yeh answer yasaha he rehay gya, 2 by 9, 3 by 9, and 4 by 9, ok?
