Answer:

1/5

Step-by-step explanation:

The question says that 3 blacks coins are in a bag as well as 3 red coins.

A coin is picked at random without replacement and another coin is picked again.What is the probability of both coins picked been a black.

P(B)= 3/6 which is also 1/2

Probability of second coin picked been black again will be

P(B) = 2/5( if one coins is picked and not replaced the total number of coins left will reduce)

Therefore,the probability of this happening will be

1/2×2/5= 1/5

bekas [8.4K]

Answer:

$660

Step-by-step explanation:

22*40 = 880 dollars. This is your gross pay.

Then, 880*0.2 (deduction of federal income tax rate) = 176 dollars

We also have to deduct the social security tax rate so, 880*0.05 = 44 dollars

Therefore, we totally have to deduct 176 + 44 dollars which is 220 dollars. 880-220 = 660.

Gasoline costs 1.05 euro per liter in France. What is the price in dollars per​ gallon?
Alecsey [184]

The price in dollars per gallon is 4.02 dollars per gallons.

<h3>How to find the price of gasoline in dollars per gallon?</h3>

Gasoline costs 1.05 euro per litre in France.

The first thing to do is to determine the equivalent amount of the same litre in dollar while in France.

Then, equate it the quantity of litres to gallons.

Hence,

1 euro = 1.01 dollars

1.05 euro = ?

cross multiply

price  = 1.05 × 1.01

price = 1.0605 dollars

1 litres = 0.264172 gallons

Therefore,

cost =  1.0605 /  0.264172

cost  = 4.01552442257 dollars per gallons

cost  = 4.02 dollars per gallons

Therefore, the price in dollars per gallon is 4.02 dollars per gallons.
