Dwindling means کم ہونا

Declining means گر رہا ہے

Explanation

Mean of a binomial distribution is given by:

  Mean = n × p

So, Mean = 4 × 0.5 = 2

Explanation

r is the carriage return escape sequence, which moves the cursor to the beginning of the current line.

It does not move to the next line, unlike n (newline).

Explanation

The equation is separable:

  dy/dx = –y

  ⇒ dy/y = –dx

  ⇒ ∫(1/y) dy = ∫(–1) dx

  ⇒ ln|y| = –x + C

  ⇒ y = Ce⁻ˣ (where C is the constant of integration)

Explanation

A die has 6 numbers: 1, 2, 3, 4, 5, 6

Even numbers greater than 2: 4 and 6 → 2 outcomes

Total possible outcomes: 6

Probability = 2/6 = 1/3

Explanation

Deciles divide an ordered data set into 10 equal parts.

Each decile represents 10% of the data distribution.

Explanation

Mutually exclusive events cannot happen at the same time.

So, P(A or B) = P(A) + P(B) when A and B are mutually exclusive.

Explanation

To find the mean, add up the values and divide by the number of values:

0 + 0 + 2 + 2 + 2 + 3 + 3 + 8 + 0 + 10 = 30

There are 10 values.

Mean = 30/10 = 3

Explanation

do-until is not a valid loop structure in C programming.

C provides for, while, and do-while loops for iteration.

Explanation

The format specifier %c is used in scanf to read a single character.

So, km must be a character variable, e.g., char km;.
