A man has three children. They are not triplets. By a remarkable coincidence, however, they were all born on the same day in different years. By another remarkable coincidence, their ages right now form a Pythagorean triple. The oldest child is nine years older than the youngest, and the middle child is two years younger than the oldest

probability that the arrow will stop on the same letter twice = (c).

Step-by-step explanation:

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = .

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6.  Arrow ston on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability =  .

Probability =  .

Therefore,  probability that the arrow will stop on the same letter twice = (c).
