## anonymous 5 years ago At the end-of-season party, the coach will draw a card from a box to determine who wins the grand prize. The box contains 100 cards. Five of the cards say "Grand Prize," 10 say "Second Place," 25 say "Third Place," and the rest are blank. What is the probability that the coach will draw a blank card on the first draw? A. 5% B. 40% C. 60% D. 100%

the probability is (100-5-10-25)/100, which is 60/100 or 60%, so C is corrct

$\frac{ \text{number of blank cards}}{\text{total number of cards}}$
