31. Which one of the following statements is false?

- A
Sample space refers to the collection of all favourable outcomes of an experiment.

- B
Collectively exhaustive events are those whose union is sample space.

- C
All the outcomes of an experiment are known as sample space.

- D
Two events are said to be independent if the happening of one does not affect the probability of happening of the other.

- Option : A
- Explanation : Sample Space: It is a set of all possible outcomes of an experiment. It is usually represented as S. For example, if the random experiment is rolling of a die, the sample
space is a set, S = [1, 2, 3, 4, 5, 6].

Similarly, if the random experiment is tossing of three coins, the sample space is, S = [HHH, HHT, HTH, THH, HTT, THT, TTH, TTT] with total of 8 possible outcomes. (H is heads, and T is Tails showing up.)

If we select a random sample of 2 items from a production lot and check them for defect, the sample space will be S = [DD, DS, DR, RS, RR, SS] where D stands for defective, S stands for serviceable and R stands for reworkable.

32. Which one of the following is a false statement?

- Option : A
- Explanation : Binomial Distribution: The binomial distribution is usually exemplified by flipping a coin. The result can have only two outcomes, heads or tails, each of which has equal probability. The probability of either outcome remains the same throughout the experiment. The binomial distribution therefore describes the probability that in a finite number of trials (coin flips), there will be a specified number of heads (successes) or a specified number of tails (failures). The general form of the binomial distributions is where n is the number of trials, r is the number of successes.
