Using the probability concept, it is found that:
a) P(girl) = 1/3, which means that 1/3 = 33% of the time, the first batter will be a girl.
b) P(boy) = 2/3, which means that 2/3 = 67% of the time, the first batter will be a boy.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, in a total of 15 people, 5 are girls and 10 are boys, hence:

Given, the rate of growth of St. Augustine grass is cm per week.
We have to find the number of weeks that the grass grow to cm.
Let's take the number of weeks be x.
In 1 week the grass grow = cm
So in x weeks the grass grow = cm
So we can write,
To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,
Now to get we will move 4 to the right side by dividing it to both sides. We will get,
So we have got the required answer.
After 3 weeks the grass grow .
Here is the answer. Please give me brainliest
Answer:
area of the square =11*11=121
area of the circle =pi r^2=pi*1^2=3.142
part a
p(hitting the circle =3.142/121=0.026 Which is closer to 0
part b
p( hitting the white portion ) =1-0.026=0.974 which is closer to 1
