Use the interactive to solve. What is the difference between –5 and 3?​

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.

Someone me! if you’re smart you can solve this!

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
