53 - 1 or 1 chance in 54 or 0.0185 or 1.85%
The event space comprises the numbers 10 to 99, 90 such numbers. The favourable events are 15, 21, 27, ... , 99. There are 15 such numbers. So the probability is 15/90 = 1/6
The probability is(the total number of numbers on the spinner minus 5)/(the total number of numbers on the spinner)Another way to express the same probability is1 - 5/(the total number of numbers on the spinner)
The probability of spinning the number 3, or any number, is 1/4 or 0.25 since there is 4 numbers total.
On the basis that numbers are a continuous variable, the probability of any particular number (or pair) is 0.
50%, or 1 out of 2. There are 12 numbers, 6 even and 6 odd, so they have equal chance of being odd or even if one is selected

The probability of selecting a 17 (or any number for that matter) is 1/20 or .05 or 5%.

The probability is 1/b.
The probability is 0.
The probability of spinning the number 3, or any number, is 1/4 or 0.25 since there is 4 numbers total.
On the basis that numbers are a continuous variable, the probability of any particular number (or pair) is 0.
The probability is 3 out of 10.
You carry out an experiment repeatedly. Then the number of times that the selected even occurs divided by the total number of trials is the relative probability for that event.
The prime numbers from one to nine are 2, 3, 5, and 7. There are nine numbers from one to nine. The probability is 4 (the number of prime numbers) over 9 (the total number of numbers). Therefore, the probability of choosing a prime number is 4/9 or about 44 percent.
50%, or 1 out of 2. There are 12 numbers, 6 even and 6 odd, so they have equal chance of being odd or even if one is selected
