Not all square roots are irrational. This can be proven by finding the perfect square roots. The sqrt. of 16, 25, and 26, for example, the answers are all rational numbers.
I hope this is what you are asking for; let me know if you need anythings else :)
An irrational number is a number that has an everlasting decimal (9.34560292348857485...). (If the decimal repeats, it is not irrational. 9.476666666...) This is false because the square root of an even number are not irrational. The square root of 16 is 4. The square root of 144 is 12.
Step-by-step explanation: It doesn't matter how many questions there are because for each question, you have a 50% chance of getting it right. So, the probability is 50%.
