The probability of spinning an even number on the first spin is 4/8 since there are 4 even numbers out of the total 8 numbers.
After spinning an even number on the first spin, there will be 7 spots left on the spinner, with 4 odd numbers and 3 even numbers. Therefore, the probability of spinning an odd number on the second spin is 4/7.
To find the probability of both events happening, we multiply the probabilities together:
(4/8) * (4/7) = 16/56 = 4/14 = 2/7
So, the probability of spinning an even number on the first spin and spinning an odd number on the second spin is 2/7.
