First you add up the red and black so see how many she has total.
45 + 60= 105
then if you need to find the probability of the red candies you put
45/ 105
then you can simplify it so it would be 8/21
45+60=105
45/105= 8/21
You move 2x to the other side of the =, divide both side by 3 and make sure it’s in slope intercept form
2x+3y=12
-2x. -2x
——————-
3y= 12 -2x
—. — —-
3. 3. 3
y=4 - 2/3x
y= -2/3x + 4
Step-by-step explanation:
"The probability of drawing a red ace followed by another ace of any color without replacement."
There are 4 aces total, 2 of which are red. After the first red ace is drawn, there will be 3 aces left. So the probability is:
P = (2/52) (3/51)
P = 1/442
"The probability of drawing a king followed by a queen with replacement."
There are 4 kings and 4 queens. So the probability is:
P = (4/52) (4/52)
P = 1/169
"The probability of drawing a 3 or a 5 followed by a 4 or a 6 with replacement."
There are 8 cards that are either 3 or 5, and 8 cards that are either 4 or 6. So the probability is:
P = (8/52) (8/52)
P = 4/169
"The probability of drawing a spade followed by a jack of any color with replacement."
There are 13 spades, and 4 jacks. So the probability is:
P = (13/52) (4/52)
P = 1/52
