Your answers would be the first and third choice.
C. would be the correct device to use in trials.
But the actual probability is:
(1-1/4)^5
243/1024
(about 23.73% chance none of the five chose vanilla)
Hi there
just keep dividing by 2 tell you get to the 10th term
that's one way of doing it
32, 16, 8, 4, 2, 1 , 1/2 , 1/4 , 1/16, 1/32
1/32 is the 10th term
You would want to divide 30 by 2/3 so you would do 30/1 times 3/2. This method is known as keep change flip or kcf (Kentucky Chicken Fried is what some people say) your final answer should come out to 90/2 which simplified is 45. Hope this helped
