3/10 is the Probability of not Drawing Blue Marbles
Step-by-step explanation:
Blue Marbles = 7
Green Marbles = 2
Red Marbles = 1
Total Marbles = 7 + 2 + 1 = 10
Probaility of Drawing Blue Marbles = 7 /10
Probability of not Drawing Blue Marbles = 1 - Probaility of Drawing Blue Marbles
= 1 - 7/10
= 3/10
or
Probability of not Drawing Blue Marbles = Probability of drawing Green or Red Marbles
= 2/10 + 1/10
= 3/10
3/10 is the Probability of not Drawing Blue Marbles
1st step because 2 times x is 2x and 2 times 3 is 6
Answer:
X=7
Y=9
Step-by-step explanation:
.y=x+2
y = 2x - 5
Use equivalents y=y so you get:
X+2=2x-5
X-2x=-5-2
-x=-7
X=7
Y=x+2=7+2=9
