Out of a class of 8 boys and 4 girls, a group of 7 people is chosen at random.
Find the probability that the group of 7 includes one particular boy.
Find the probability that the group of 7 includes at least 2 girls.

Out of a class of 8 boys and 4 girls, a group of 7 people is chosen at random.

Find the probability that the group of 7 includes one particular boy.  Find the probability that the group of 7 includes at least 2 girls?

boys= 8

girls= 4

total= 12

probability that the group of 7 includes a boy= 8/12= 2/3

probability that the group of 7 includes at least 2 girls= 4/12= 1/3

Step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

i can't solve unless i know what the line is
