Answer:

The probability of drawing a second red card, since the first card is red is 25/51

Step-by-step explanation:

The probability of drawing a second red card since the first Card is red is:

P (R2 | R1) = P (R2 and R1) / R1

So:

P (R2 | R1) = (25/102) / 1/2

P (R2 | R1) = 25/51

Therefore the correct option is option 2.

the probability of drawing a second red card, since the first card is red is 25/51

You get a 15% raise at your job and now make $13.50 per hour. What was you previous rate of pay per hour?
Anestetic [448]
<h2>We know:</h2>

You currently make $13.50 an hour. You've earned a 15% pay raise. You want to find out your previous rate of pay per hour.


<h2>Steps:</h2>

1.) Convert 15% to a decimal, which equals 0.15


2.) Multiply your current earnings with the percentage in decimal form (0.15)

$13.50 (current pay per hour) x 0.15 (percentage in decimal form) = $2.025 (difference between your previous wage and your current wage)


3.) Subtract the difference of your previous wage and current wage with your current earnings

$13.50 (current pay per hour) - $2.025 (difference between previous and current wage) = $11.475 (previous pay per hour)


4.) Since this is talking about wage, rounding is not applicable. In other cases, your number would be rounded off to $11.48, however you can't add what you don't have, so you would have to round down.


<h2>You were previously making $11.47 an hour.</h2>
