Answer 1

Answer:

For part A the answer is B (the second one)

For part B I would say there is a 50 percent chance for the chip to land on red so the students should have the last chip land on red on the 9th trial because there would be a more than fifty percent chance for the chip to land on red.

first trial 128/2 = 64,

second trial 64/2 = 32,

third trial 32/2 = 16,

fourth trial 16/2 = 8,

fifth trial 8/2 = 4,

sixth trial 4/2 = 2,

seventh trial 2/2 = 1,

eighth trial 1 chip 50/50 chance,

9th trial 1 chip 75/25 chance for the chip to land on red.

Answer 2

Let's check

See the word off side so it is deducted ,

• It will form a geometric sequence

General formula is ar^n-1

So correct answer is

• f(n)=128(1/2)^n
