Question

240 times by 8 congruent out of 3

Answer 1

To determine the number of times the spinner will land in a prime number first we need to determine the probability of the spinner landing on a prime number. The probability is equal to the number of prime numbers divided by the total number of numbers. There are 6 prime numbers, those are 1, 3, 5, 7, 11, and 13.

Therefore, the probability is:

`P=(6)/(8)=(3)/(4)`

Now, the number of expected times the spinner will land in a prime number is the number of times it is spun multiplied by the probability:

`n=(3)/(4)*240=180`

Therefore, we can expect that the spinner will land on a prime number 180 times.
