a spinner is divided into 10 equal sections numbered 1 through 10. if the arrow is spun twice, what is the probability the first number will be even and the second number will be a 7
Explanation: There are 10 possible outcomes, of which 5 are even. The chance of it being even is 1/2 or 50%. 1 of the 10 outcomes is a 7. The chance of it being a 7 is 1/10 or 10%. You then do 10% x 50% which results in 5%.
