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
Answer:
x = 5.142
Step-by-step explanation:
<em>2=-74+14x</em>
if you want to make x the subject (work out its value), you need to single out x
1) the first thing that we can do is get rid of the -74
2) do this by adding it on to both sides of the equation. This is called the inverse
<em>2+-74=-72 -74+14x=14x</em>
<em>-72=14x</em>
3) to get x on its own, we now need to get rid of the 14
REMEMBER:<em> 14x = 14×x</em>
4) We do the inverse by dividing both sides by 14
<em>-72÷14=-5.142..</em>.
its surprising that its not an integer
<em>5.142=x</em>
<em>x=5.142 </em>
PLEASE LET ME KNOW IF THIS IS CORRECT
Answer:
d , 10
Step-by-step explanation:
-8 / -4 = positive 2, + (6+2) (eight) = 10
Answer: I'm assuming you want to know how much surface area his fence is, so 40
Step-by-step explanation: First we can divide 15 by 3 to get 5, and then multiply 5 by 8. This gives us 40, which is our answer.
Hope this helps :)
