00:00Okay, in this question, example number 3, suppose we have a dye. Dyes of radicular. Okay, this is our dye.
00:30This is our dye. Now, dyes has how many? 6 faces, right? This is our first one number, then this may be having 3 numbers or 2 numbers.
00:56We have 4 numbers here. Okay, and then, so how many numbers are there on a dye? 1, 2, 3, 4, 5 and 6.
01:13Okay, now, question number 1, what is the probability of getting a number greater than 4?
01:21Now, probability of, now we have to write here, we have to write P of E.
01:28event that, the probability, probability of getting, a number, greater than,
01:554, okay, is equal to, P of E is equal to what? P of E is equal to favorable outcome, divided by total outcome.
02:13Now, what is total outcome? 1, 2, 3, 4, 5 and 6. So, 6 are the total outcome.
02:18And greater than 4 means what? 5 and 6. This is our answer, 5 and 6.
02:23So, how many digits are there? 1, 5 and second is 6. So, 2. 2 digits divided by 6.
02:30So, 2 into 1 divided by 2 into 3, 2 cancel. We have 1 by 3. Okay, so our answer is 1 by 3.
02:42Now, what is second one? What is the probability of getting, second one?
02:46second one. What is the probability of getting number less than or equal to 4? Here, less than or equal to, less than 4? This one. And equal to 4? This one.
02:59Means what? 1, 2, 3, 4. Okay. So, total outcome? 6. And favorable outcome? 4. If the event, P of any F, P of F,
03:10the probability of getting a number less than or equal to 4, less than or equal to 4.
03:27Total number? 4. How much? Total favorable outcome? 4. And total number? 6. So, our answer is,
03:372 into 2 divided by 2 into 3. 2 to cancel. We have 2 by 3. This is our answer.
