Question
1) The prizes at a carnival tossing game are different stuffed animals. There are 34 tigers, 27 bears, 12 hippopotamuses, 16 giraffes, and 22 monkeys. The carnival manager randomly selects a prize when a player wins the game. Determine the probability that the prize selected is not a bear. Give your answer as a decimal, precise to three decimal places. (please show work)
AND
2) One day, Karen bought 20 random cans of soup from a grocery store. Suppose that 3% of cans sold at that particular grocery store are dented, and assume the store's inventory is large enough that no individual customer's purchase affects the dent rate for the remaining cans.
What is the probability that Karen has bought at least one dented can? Express your answer as a percentage precise to one decimal place. (please show work)
Explanation / Answer
As multiple questions are posted, only the first one will be answered.
1. P(Prize is a bear) = Number of bears / Total number of animals
= 27 / (34+27+12+16+22) = 0.243
P(Prize is not a bear) = 1 - 0.243 = 0.757
