A single little brown bat can eat up to 1,000 mosquitoes in a single hour. Express in scientific notation how many mosquitoes a
Nastasia [14]
Our final answer must represent "number of mosquitos."  This verifies that the correct calculation would be

1000 mosquitos              10.5 hours
-----------------------  x   --------------------
         1 hour                           1

Multiply this out.  Note that "hours" will cancel.

Whats your result?

Supposing that your result looked like   xxxxx times 10^0,

you'd convert this into scientific notation by moving the decimal place four units to the left (obtaining x.xxx) and then increasing the exponent of 10 from zero to four (obtaining 10^4).

Then your answer would have the form x.xxx times 10^4 (mosquitos)

What is the probability of drawing four queens from a standard deck of cards, given that the first card drawn was a queen? Assum
aleksley [76]

The probability of drawing three queens from a standard deck of cards is 0.000162.

<h3>What is the probability?</h3>

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

Total cards = 54

No. queens in a deck = 4

Probability of drawing a queen card = 4/54

Now that 1 queen has been taken, the no. of cards becomes = 53

and

no. of queens = 3

Probability of getting a queen again = (3/53)(4/54)

Two queens have already been removed.

No. of cards in the deck = 52

No. of queens in the deck = 2

Probability of drawing three queens

= (2/52)(3/53)(4/54)

= 0.000162 approximately

The probability of drawing three queens from a standard deck of cards is 0.000162.
