Question

if you flip a coin, it will come up heads.
the chick inside an egg is either male or female.
if you spin a spinner with 5 equal sections, it will land on 2.
you pick a green marble out of a bag that contains 1 red marble, 1 blue marble, and 1 green marble.
which one of these events has a probability closest to 0?

Explanation:

Step1: Calculate probability of each event

• Coin flip (heads):

A fair coin has 2 possible outcomes (\(n = 2\): heads or tails). The probability of getting heads \(P(\text{heads})=\frac{1}{2}=0.5\)

• Chick gender (male or female):

Assuming equal - likelihood (in a simple model), there are 2 possible genders. So \(P(\text{male}) = P(\text{female})=\frac{1}{2}=0.5\)

• Spinner (landing on 2):

The spinner has 5 equal - sections (\(n = 5\)). The probability of landing on 2 is \(P(\text{landing on }2)=\frac{1}{5}=0.2\)

• Picking a green marble:

The bag has \(1 + 1+1=3\) marbles (\(n = 3\)), and 1 green marble. So \(P(\text{green marble})=\frac{1}{3}\approx0.33\)

Answer:

If you spin a spinner with 5 equal sections, it will land on 2.
