You randomly draw a marble from a bag of marbles that contains 7 blue marbles, 2 green marbles, and 1 red marble.
What is P (not drawing a blue marble)
Answers
Answer:
total=10
so P(not drawing to blue)= 3/10
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
