a card is chosen from a standard deck of cards. what is the probability that the card is a queen, given that the card is a club?

Dmitrij [34]

Answer:

Probability that card is queen given that card is club is $\frac{4}{13}$

Step-by-step explanation:

Given : A card is chosen from a standard deck of cards.

To find : What is the probability that the card is a queen, given that the card is a club?

Solution : It is the conditional probability

$P(A|B)=\frac{P(A\cap B)}{P(B)}$

Let A is probability that card is queen.

Let B is the probability that card is a club.

Probability that card is queen given card is club $P(A\cap B)=\frac{4}{52}=\frac{1}{13}$

Probability that card is club from deck of 52 cards $P(B)=\frac{13}{52}=\frac{1}{4}$

To find probability that card is queen given that card is club $P(A|B)$

$P(A|B)=\frac{P(A\cap B)}{P(B)}$

$P(A|B)=\frac{\frac{1}{13}}{\frac{1}{4}}$

$P(A|B)=\frac{1\times4}{13\times 1}=\frac{4}{13}$

Therefore, Option A is correct.

Probability that card is queen given that card is club is $\frac{4}{13}$

A hiker walks along a path and comes to a cliff. He wants to find out how high the cliff is, so he ties a 110 foot cable to a ro

solmaris [256]

Answer:

B. sine; 46.5 feet high

Step-by-step explanation:

In this case, we use trigonometric ratio.

Assuming the horizontal ground, the cable and the height of the cliff forms a triangle,

The cable is the hypotenuse, the height of the cliff is opposite to the angle formed by the cable and the horizontal ground.

Thus; the most appropriate function is sine

Such that;

Sine θ = Opposite/Hypotenuse

Where; θ = 25°, opposite is the height of the cliff and hypotenuse is the cable, 110 ft

Therefore;

Sine 25° = Opp/ 110

Hence;

Opp = 110 ft × sine 25°

= 46.488 ft

= 46.5 ft

Therefore;

The function is Sine, and the height of the cliff is 46.5 ft high
