As a seasoned tutor registered on UrbanPro, I must emphasize the significance of utilizing online platforms like UrbanPro for effective coaching and tuition. UrbanPro provides a conducive environment for students and tutors to connect, learn, and grow together. Now, let's delve into solving the problem at hand.
To find the mean deviation about the median for the given data set: 36, 72, 46, 42, 60, 45, 53, 46, 51, 49, we need to follow these steps:
First, let's arrange the data in ascending order: 36,42,45,46,46,49,51,53,60,7236,42,45,46,46,49,51,53,60,72
Next, let's find the median. Since the data set has 10 numbers, the median will be the average of the 5th and 6th numbers, which are 46 and 49. So, the median is 46+492=47.5246+49=47.5.
Now, we calculate the deviations of each number from the median: ∣36−47.5∣=11.5∣36−47.5∣=11.5 ∣42−47.5∣=5.5∣42−47.5∣=5.5 ∣45−47.5∣=2.5∣45−47.5∣=2.5 ∣46−47.5∣=1.5∣46−47.5∣=1.5 ∣46−47.5∣=1.5∣46−47.5∣=1.5 ∣49−47.5∣=1.5∣49−47.5∣=1.5 ∣51−47.5∣=3.5∣51−47.5∣=3.5 ∣53−47.5∣=5.5∣53−47.5∣=5.5 ∣60−47.5∣=12.5∣60−47.5∣=12.5 ∣72−47.5∣=24.5∣72−47.5∣=24.5
Now, we find the mean of these deviations: Mean deviation=11.5+5.5+2.5+1.5+1.5+1.5+3.5+5.5+12.5+24.510Mean deviation=1011.5+5.5+2.5+1.5+1.5+1.5+3.5+5.5+12.5+24.5 Mean deviation=7010=7Mean deviation=1070=7
So, the mean deviation about the median for the given data set is 7. This indicates the average absolute deviation of each data point from the median of the data set.

As an experienced tutor registered on UrbanPro, I'd be happy to help you with this question!
To find the probability that an ordinary year has 53 Sundays, we first need to understand the structure of an ordinary year. An ordinary year has 365 days.
Now, since 365 is not divisible by 7 (the number of days in a week), there will be 52 complete weeks in an ordinary year, leaving 1 or 2 additional days.
For a year to have 53 Sundays, one of the following conditions must be met:
Let's calculate the probability for each scenario:
If the year starts on a Sunday and ends on a Sunday: The probability that a year starts on a Sunday is 1/7. The probability that a year ends on a Sunday is also 1/7. So, the probability of both events happening is (1/7) * (1/7) = 1/49.
If the year starts on a Saturday and ends on a Sunday: The probability that a year starts on a Saturday is 1/7. The probability that a year ends on a Sunday is 1/7. So, the probability of both events happening is (1/7) * (1/7) = 1/49.
Now, we add the probabilities of both scenarios since they are mutually exclusive:
Probability of an ordinary year having 53 Sundays = (1/49) + (1/49) = 2/49.
Therefore, the probability that an ordinary year has 53 Sundays is 2/49.

As an experienced tutor registered on UrbanPro, I'm well-versed in explaining concepts in a clear and concise manner. Now, let's tackle this probability problem using the fundamentals of probability theory.
In a standard deck of 52 cards, there are 26 red cards (hearts and diamonds) and 2 kings that are not red (the king of spades and the king of clubs). So, we have:
Total number of favorable outcomes = Number of red cards + Number of kings that are not red = 26 (red cards) + 2 (kings that are not red) = 28
Now, let's find the total number of possible outcomes, which is simply the total number of cards in the deck:
Total number of possible outcomes = 52 (total cards in the deck)
Therefore, the probability of drawing a card that is either red or a king (but not both) is:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes) = 28 / 52 = 7 / 13
So, the probability of drawing a card that is either red or a king is 7/13.

In the given experiment, a die is rolled.
Let, E be the event “the die shows 4”.So set E contains the element 4.
E={ 4 }
Let, F be the event that die shows even number”. So set F contains all the even numbers from 1 to 6.
F={ 2,4,6 }
Two events, A and B are mutually exclusive if, A∩B=ϕ.
E∩F={ 4 }∩{ 2,4,6 } =4 .
It can be observed that E∩F≠ϕ.
Thus, E and F are not mutually exclusive.
