Answer 1

3/5

Explanation:

Concepts + Application + Solution

We can write the probability of this event happening like this:

• (number of prime numbers)/(total number of sections)

For recap, a prime number is a number that's greater than 1 whose only factors are 1 and itself. Take the number 7 for example; its factors are only 7 and 1.

Given this information above, let's find the prime numbers in the spinner.

• 1: not prime (not greater than 1)
• 2: prime
• 3: prime
• 4: not prime (divisible by 2)
• 5: prime

As you can see, we have 3/5 numbers that are prime, making the probability of landing on a prime number 3/5.

Answer 2

Prime numbers between 1 and 5 = 2,3,5
To get the probability we get the amount of numbers that are prime and put them over the total number of sides of the spinner which equals: 3/5
