Astudent is asked to calculate the value of 83 using the identity (x − y)3 = x3 − 3x2y + 3xy2 − y3. the student's steps are shown below. step 1: 83 = (10 − 2)3 step 2: = (10)3 − 3(10)2(−2) + 3(10)(−2)2 − (−2)3 step 3: = (1,000) + (600) + (120) + (8) step 4: = 1,728 the correct answer should be 512. in which step did the student make his first error?
step 1
step 2
step 3
step 4

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
