A3-card hand is dealt from a standard 52-card deck, and then one of the 3 cards is chosen at random. if only one of the cards in the hand is a 3, what is the probability that the chosen card is a 3?
the probability that the chosen card is a 3 is?
(simplify your answer. type an integer or a fraction.)

1/3

Step-by-step explanation:

Once you know there is a 3 in the hand, and only one card is drawn from the cards in the hand, then the probability of drawing the 3 is 1/3.

P (chosen card is 3) =

Step-by-step explanation:

We are given that a 3-card hand is dealt from a standard 52-card deck, and then one of the 3 cards is chosen at random.

Given that only one of the cards is a 3, we are to find the probability that the chosen card is a 3.

Since only one card is a 3 and one card is chosen so:

P (chosen card is 3) = 1 / 3

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
