PROBABILITY SAMPLING

Probability Sampling



Probability Sampling

Q The coin is thrown 5 times so the possibilities of

- throwing 5 heads are (3/5)

- throwing 4 tails (2/5)

- throwing 3 heads and 2 tails (3/5) & (2/5)

Independent Events

Two or more events are independent when the occurrence or non-occurrence of an event has no effect on the probability of occurrence of another event (or events).

A typical case of independent events is sampling with replacement, ie, after taking the sample is returned back to the town where it was obtained.

Q If a dice is thrown 4 times, the probability of:

- throwing 4 sixes is (4/24)

- throwing ...
