Question

There are 4 boys and 2 girls in the Science Club. The members draw straws to determine which two members will give the demonstration at the science fair. Which simulation could be used to determine the probability that at least one of the demonstrators will be a girl? A. toss a coin two times B. spin a spinner with 4 equal sections two times C. roll a six-sided number cube two times D. pick a card from 10 cards two times

Answer 1

Answer:

B. spin a spinner with 4 equal sections two times.

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.

The answer is option B. spin a spinner with 4 equal sections two times.
