An experiment consists of drawing one card from a bridge deck. The sample space contains 52 outcomes, one for each of the 52 car

irina [24]

Answer: a) $\dfrac{1}{13}$

b) $\dfrac{2}{13}$

c) $\dfrac{1}{4}$

d) $\dfrac{1}{2}$

Step-by-step explanation:

Formula for probability = $\dfrac{\text{Number of favorable outcomes}}{\text{Total outcomes}}$

The total number of cards in a deck = 52

a) Number of cards having queen =4

Then the probability that a queen is drawn = $\dfrac{\text{No. of cards having queen}}{\text{Total cards}}$

$=\dfrac{4}{52}=\dfrac{1}{13}$

c) Number of cards having King= 4

Then , the number of cards having a queen or king =4+4=8

Then the probability that a king or queen is drawn = $\dfrac{\text{No. of cards having king or a queen}}{\text{Total cards}}$

$=\dfrac{8}{52}=\dfrac{2}{13}$

c) Number of cards having heart = 13

Then the probability that a heart is drawn = $\dfrac{\text{No. of cards having heart}}{\text{Total cards}}$

$=\dfrac{13}{52}=\dfrac{1}{4}$

d) Number of red cards = 26

Then the probability that a red card is drawn = $\dfrac{\text{No. of red cards}}{\text{Total cards}}$

$=\dfrac{26}{52}=\dfrac{1}{2}$

Question 3 options:

melomori [17]

The height of an object can be represented as a function of time.

It takes the rocket 25 seconds to hit the ground

The height function is given as:

$\mathbf{h(t) = 400t - 16t^2}$

When the rocket hits the ground, we have:

h(t) = 0

So, the height function becomes

$\mathbf{ 400t - 16t^2 = 0}$

Rewrite as:

$\mathbf{ 16t^2 = 400t}$

Divide both sides by 16t

$\mathbf{ t = 25}$

Hence, it takes the rocket 25 seconds to hit the ground

Mika used division to rewrite 5/40

ella [17]

Hello there, and thank you for posting your question here on brainly.

To convert a decimal to a percent, you have to make the decimal a whole number by getting rid of the decimal point, and then at a % sign.

0.125 ===> 125

125 ===> 125%

Hope this helped!! ☺♥

You pay off the bigger one first because if you don't do that one first the amount of money in the credit card will just gain interest and have more, and you won't be able to pay the big amount.
