There are six girls and seven boys in a class a team of 10 players is to be selected from the class if the selection is random what is the probability of selecting a team of four girls and six boys.
.308
.367
.461
.667

The answer is 0.367. The total possibilities of choosing 10 players is C₁₃¹°=C₁₃³=13*12*11/(3*2*1). The possibilities of choosing 4 girls and 6 boys is C₆⁴ * C₇⁶ = C₆² * C₇¹ = 6*5/2 * 7. So the probability is 0.367.(possibility of first divide by the second)

answer:

f(x) = 100/(2ˣ)

step-by-step explanation:

looking at the graph, i got the points

(0, 100)

(1, 50)

(2, 25)

(3, 12.5)

it seems that the functions is exponentially decaying by half for every x-value increase.

so, my function must have the graph start at 100 and decay by 1/2 every time giving me the equation:

f(x) = 100 * (1/2)ˣ

f(x) = 100 * (1ˣ/2ˣ)

f(x) = 100 * (1/2ˣ)       , 1ˣ will always be equal to 1

f(x) = 100/(2ˣ)
