Answer:

\frac{25}{102}

Step-by-step explanation:

"AND" means Multiplication, and

"OR" means Addition (in probability)

We want Both cards to be black, that means 1st card black "AND" 2nd card black. So we find individual probabilities and MULTIPLY.

There are 26 black cards from 52 total cards in a normal deck.

P(1st card black) = 26/52 = 1/2

Now, since we HAVEN'T REPLACED, there are now 25 black cards out of 51 total cards. So

P(2nd card black) = 25/51

Now we multiply:

P(both black) = \frac{1}{2}*\frac{25}{51}=\frac{25}{102}

Angel has an action figure collection of 300 action figures. He keeps 267 of the action figures on his wall. What percentage of
Veseljchak [2.6K]

Answer:

89% of Angel's action figure collection keeps on his wall.

Step-by-step explanation:

<u>Percentages</u>

To calculate the X% of a quantity Y, we must multiply both numbers and divide by 100:

X% of Y = X * Y / 100

For example, 15% of 780 = 15 * 780 / 100 = 117

If we want to know what percentage is m with respect to n, we proceed as follows:

percentage = m / n * 100%

Anges has a 300 action figures collection, 267 of which are kept on his wall. Here m=267, n=300, thus:

percentage = 267 / 300 * 100% = 89%

89% of Angel's action figure collection keeps on his wall.

Given that

Carmen saved 592 pennies.

Her sister saved 128 pennies.

Together, they put 250 pennies in wrappers and took them to the bank

We need to find out the total number of pennies Carmen and her sister have left

So,

= 592 pennies + 128 pennies  - 250 pennies

= 470 pennies

= 500 pennies
