Answer:
2/3
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that there are 10 balls of which 3 green, 3 red, and the rest yellow
Number of yellow balls = 10 - 3 - 3 = 4
Probability of picking a;
Green ball = 3/10
Red ball = 3/10
Yellow ball = 4/10
If two balls are picked without replacement, the probability that one is at least yellow will be
YR RY YG GY YY
= 4/10*3/9 + 3/10*4/9 + 4/10*3/9 + 3/10*4/9 + 4/10*3/9
=12/90 *5
= 2/3
Answer:
x= -9
Step-by-step explanation:
1. distribute
3(+1)=2(−3)
so it would look like this:
3+3=2x-6
2. subtract 3 from both sides
It would look like this:
3x=2x-9
3. subtract 2x from both sides
It would look like this:
x= -9
And that is your answer!!
Answer:
there are two solutions:
a) 
, and
b) 
Step-by-step explanation:
In the equation: 
, since a perfect square with the unknown "y" is isolated on the left of the equal sign, we start by applying the square root on both sides of the equality, and then on isolating the unknown:
Therefore there are two solutions:
a) , and
b)
