Spin a spinner numbered 1-8 two times, land on two the first time and land on a factor of 8 the second time
Accepted Solution
A:
The correct probability is 1/16.
Explanation:
There is 1 section marked 8 out of 8 sections. This makes the probability of landing on an 8 1/8.
The factors of 4 on this spinner are 1, 2, 4 and 8. This makes 4 sections out of 8, which makes the probability of landing on a factor of 8 equal 4/8=1/2.
Together, the probability of both events would be 1/8(1/2) = 1/16.
