Aspinner labeled 1 to 7 gives each of the numbers 3, 5, and 7 a 3
10
chance of being landed upon. the chance of landing on each of the
other four numbers is equal.
a) if the spinner is spun 1,300 times, how many times do you
expect it to land on the 5? show all work.
b) knowing the probability of landing on a 3, 5, or 7, you can find
the probability of landing on the 1, 2, 4, or 6. find the
probability of not landing on a 3, 5, or 7. divide this by number
of numbers remaining to find the probability of landing on a 1, 2,
4, or 6. show all work finding the probability of landing on one
of these numbers.
c) if the spinner is spun 1,500 times, how many times do you
expect it to land on the 2?
