Aplayer is randomly dealt a sequence of 13 cards from a deck of 52-cards. all sequences of 13 cards are equally likely. in an equivalent model, the cards are chosen and dealt one at a time. when choosing a card, the dealer is equally likely to pick any of the cards that remain in the deck. what is the probability the 13th card dealt is a king?

Answer is 1/13

Step-by-step explanation:

Here we are not intimated about the first (01) twelve (12) cards that are shown, the probability that the thirteenth (13) card dealt is a King, if this is the same as the probability that the (01) first card shown, or in fact any particular card dealt is a King, then it equals:

=4/52

=1/13 ANS

Since the y term is squared and the co-efficient of the squared term is positive, the parabola open towards right.

Smaller the co-efficient of squared term, which is known as the leading co-efficient wider will be the graph. So graph of x = 2y² will be wider.

Therefore, the correct answer is option B. Both parabola open right and x = 2y² is wider than x = 8y²
