The answer to this question would be: 85/99
In this question, Suzan is taking 8 marble from a bag containing 4 red marbles, 4 green ones, 2 white ones, and 2 purple ones. The total marble in the bag should be: 4+4+2+2= 12. The question is how much the probability to get <4 red marble. In this question, the green, white and purple is not specified so you can join them into not red group. It will be easier to find the probability of "have all the red one" which mean Suzan take 4 red marble and 4 not-red marble<span>
Ways to take 8 marble out of 12=12C5= 12!/4!8!= </span>495
Ways to take 4 red marble out of 4= 4C4= 1
Ways to take 4 not red marble out of 8= 8C4= 8!/4!4!= 70
Probability to <span>have all the red ones= 1*70/495= 14/99
</span>Then the probability does not have all the red ones= 99/99 - 14/99= 85/99
Answers: A, C, D
Explanation: Let (x-3)=0. x then equals 3. Substitute f(3) into each equation, and the ones which equal 0 are the answer.
Answer:
7/4 or 1.75 drops
Step-by-step explanation:
In one gallon there are 128 ounces, if it takes 28 drops of coloring to turn 128 ounces of milk green then:
28/128
7/32
it takes 7/32 drops of food coloring to turn one ounce of milk green.
for 8 ounces, you multiply it by 8:
8*7/32
7/4≈1.75
∴ It would take 1.75 or 7/4 drops of coloring to turn 8 ounces of milk green.
