J. J. Redick is an excellent free throw shooter and makes 90% of his free throws (i. e., he has a 90% chance of making a single free throw). Assume that free throw shots are independent of one another. Find the probability J. J. Redick will make five consecutive free throws.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
