1/2
It depends on the spinner: how many sides it has, whether or not they are the same size, what numbers are on the spinner.
There are ten possible events: that the spinner shows one of the number from 1 to 10. The probability of each of these events is the same and equals 1/10, 0.1 or 10%
For a die it is 1/3. For anything else (a spinner, for example), there is not enough information.For a die it is 1/3.

It is 0.4
The probability of rolling an even number on a die is 3 in 6 or 1 in 2. The probability of rolling a prime on a die is 3 in 6 or 1 in 2, but one of those primes is also even. Simply add the probabilities and you find that the probability of rolling an even number or a prime on a die is 5 in 6.
The probability of spinning the spinner and landing on an odd number depends on the number of odd numbers on the spinner and the total number of numbers on the spinner. If there are 3 odd numbers on the spinner and a total of 6 numbers, then the probability of landing on an odd number is 3/6, which simplifies to 1/2 or 50%.
The probability is one in four, or 25%.
The answer depends on the number of sides on the spinner and what numbers are on it.
The probability is 3/7.
The probability is 5/9.
