The probability is a ratio of the possible events to the total events. The total is 52 cards, so the denominator is 52. The individual properties of the specific cards are the following:

Any face or number cards is 4/52, because there are 4 cards for each symbol. On the other hand, each symbol like heart, diamond, club or spade would each have a probability of 13/52 (counting numbers 2 to 10, Ace card, and the 3 face cards). Also, there are 26 each of red and black cards. Furthermore, the words 'or' and 'and' are hint words. When you see 'or', you have to add their individual probabilities. If you see the word 'and', you'll have to multiply them. With that said, the solution is as follows:

a.) P = 4/52 + 4/52 + 4/52 = 3/13
b.) P = (13/52 + 13/52 + 4/52)(26/52) = 15/52
c.) P = 13/52
d.) P = 13/52 + 13/52 + 13/52 = 3/4

The wholesale cost of a pair of sandals at a shoe store is $22.60. The markup for the sandals is 45%. What is the selling price
uysha [10]

Answer:

The selling price of sandals is: $32.77

Step-by-step explanation:

Mark up is the price that is added to the cost price of a product for profit.

Given

Price of sandals = $22.60

Mark up = 45%

To find the price with mark up, we will find the amount of mark up and then add it to the cost price of sandals.

Mark\ up = 45\%\ of\ 22.60\\= 0.45*22.60\\=10.17

The mark up is $10.17

Now,

Selling\ price = Cost + mark\ up\\= 22.60+10.17\\=32.77

Hence,

The selling price of sandals is: $32.77

X and Y = 66.5°.

Step-by-step explanation:

I am assuming that X and Y are the base angles, which are equal in an isosceles triangle.

X = Y = (180 - 47) / 2
