Answer:
<u>B. spin a spinner with 4 equal sections two times.</u>
Step-by-step explanation:
There are 4 boys and 2 girls in the Science Club.
2 members will give the demonstration at the science fair.
And at least one of the demonstrators will be a girl.
So, it is convenient to choose a simulation method with 4 outcomes.
The suitable simulation is spin a spinner with 4 equal sections two times.
The first time of the spinner we will choose a boy, each section from the four section will represent one boy.
The second time, we will choose a girl, each 2 section from the four sections will represent one girl.
<u>The answer is option B. spin a spinner with 4 equal sections two times.</u>

To calculate the areas i’m pretty sure u need to do L x W so it would be .. 644 in2?
Because the drawings are independent, the probability is the product of the probabilities of winning each drawing:
1/C(56, 3) × 1/23 = 1/(27,720×23) = 1/637,560
_____
C(n, k) = n!/(k!(n-k)!)
C(56, 3) = 56*55*54/(3*2*1) = 56*55*9
