B. Is the answer to your question.
It would be the last one because uvw is congruent to xvy
hope it helps :)
You have 4 options:
4 cards: because you draw cards and don't replace them your chance p changes on every trial, so it can't be a binomial experiment
roll 2 dice until...: a binomial experiment must have a consistent amount of trials, by doing an action until some condition is fulfilled violates this as the amount of trials or throws in this case is random
ask 9 people: there are three options, binomial experiments can only have 2
the only option left is the spinner, which is a binomial experiment
Pi divided by 2 is <span>1.57079632679 so anything bigger than 0 and less than that number should be between.</span>
