Step by step solution
Step 1 of 3
(a)
Let, P(K) denote the probability that all four cards are king drawn from a deck of cards without replacement. Outcome of each draw is independent of other, before or after, we can apply multiplication rule of probability and rule of empirical probability, ie;
Formula for Empirical Probability:
Given a frequency distribution, the probability of an event being in a given class is
P(E) =
This probability is called empirical probability and is based on observation
Multiplication Rule 1:
When two events are independent, the probability of both occurring is,
P(A and B) = P(A) . P(B)
Applying the above equations:
There are 4 kings of different suits in a deck of cards.
P(K) = P (King in 1st draw). P (King in 2nd draw). P (King in 3rd draw). P (King in 4th draw)
P(K) =
