सही: ० / ०
-
When a fair die is rolled once, the probability of getting an even number is:
सही उत्तर: क) 1/2
The even numbers are 2, 4 and 6, giving 3 favourable outcomes out of 6, so P = 3/6 = 1/2. 1/6 is the probability of getting one particular number.

If the probability of an event E is P(E), the probability of E not happening is:
सही उत्तर: ख) 1 − P(E)
An event and its complement together make up all outcomes, so P(E) + P(not E) = 1. Hence P(not E) = 1 − P(E).

When a fair coin is tossed once, the probability of getting a head is:
सही उत्तर: ग) 1/2
There are 2 equally likely outcomes (head and tail), and 1 of them is favourable, so P = 1/2. A probability can never exceed 1.

The probability of an impossible event is:
सही उत्तर: घ) 0
An impossible event can never happen, so its probability is 0. A certain (sure) event has probability 1.

The cumulative frequency curve is also known as:
सही उत्तर: घ) Ogive
An ogive is drawn by plotting cumulative frequencies, and it can be used to find the median and quartiles. A histogram uses adjacent bars for class frequencies.

-
The difference between the largest and smallest values in a data set is called the:
सही उत्तर: क) Range
Range = largest value − smallest value; it is the simplest measure of dispersion. Quartiles divide ordered data into four equal parts.

-
The median of 3, 9, 5, 11, 7 is:
सही उत्तर: ख) 7
Arranged in order: 3, 5, 7, 9, 11; the middle (3rd) value is 7. 5 is the middle of the unsorted list, a common mistake.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The value that occurs most frequently in a set of data is called the:
सही उत्तर: ग) Mode
The mode is the most frequent value. The median is the middle value when the data are arranged in order.

The arithmetic mean of 4, 8, 12, 16 and 20 is:
सही उत्तर: ग) 12
Mean = sum ÷ number of items = 60 ÷ 5 = 12. 60 is only the sum before dividing.

-
The value of cos 90° is:
सही उत्तर: घ) 0
cos 90° = 0 and sin 90° = 1. tan 90° is undefined because cos 90° = 0 would be the denominator.
