Sophie is a dog that loves to play catch. Unfortunately, she isn't very good, and the probability that she catches a ball is only 0.3. Let x be the number of tosses required until Sophie catches a ball. (a) Does x have a binomial or a geometric distribution? ◇ binomial ○ geometric (b) What is the probability that it will take exactly two tosses for Sophie to catch a ball? P(exactly two tosses) = (c) What is the probability that more than three tosses will be required? P(more than three tosses) =
