Question

1. Bill empties his jar of coins onto the floor. If the probability of all the coins landing on tails is 1/32, then what is the best answer for how many coins Bill has?
32
16
5
6

Answer 1

16 each coin gives 1/2 of a chance
If there's 1/32 chance of landing on tails then there's also 1/32 chance for heads
32/2=16
