In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).
Since we are interested in pulling a black card first, the probability is 26/52.
Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).
Now that we want to pull a red card, we know that the probability will be 26/51.
Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)
The answer we are given is 0.2549
Answer:
It would be a 3/4 chance that he will pull the right 4 coins.
Step-by-step explanation:
Answer:
A. $213.75
Step-by-step explanation:
If we add up all the numbers listed, we get a sum of 2565.
Divide $2,565 by how many numbers we added. We added 12 numbers.
2,565 ÷ 12 = 213.75.
Therefore, the average is $213.75.
If y varies inversely as x, then we write it as:
y = k/x
where k is some constant.
If we multiply both sides of this equation by x we get an equation for k:
k = x*y
We are given that y=4 when x=7, therefore:
k = 7*4 = 28
Put this back into our original equation to get:
y = 28/x
The correct expression of the inequality expression is 21% > 1/5
<h3>How to complete the inequality expression?</h3>
From the question, the expression is given as
21% < or > 1/5
We start by converting the above expression to the same form
Take for instance, we convert the expressions to decimals
So, we have
21% = 0.21
1/5 = 0.20
This gives
0.21 < or > 0.20
When the above numbers are compared, we have
0.21 is greater than 0.20
This means that we make use of the inequality symbol >
So, we have
0.21 > 0.20
Substitute 21% = 0.21 and 1/5 = 0.20
21% > 1/5
Hence, the complete inequality is 21% > 1/5
