A. 28
B. 29
C. 30
D. 36


Part B

What is the probability of landing on purple select all that apply.

A. 6/16
B. 9/16
C. 0.56
D. 16/3

Answer 1

Part A Answer = A=28

Part B Answer is B = 9/16 + C =0.56

Explanation:

1 = A. 28 This is because the percentage rate works out at 43.75%

2. 9/16 also, 0.56 This is because 9/16 has decimal 0.56 we can work this out by looking at the inverse of 1 ; 1= 16 16/9 = 1.77/3.17 which adds to 4.94 = 10 x 0.49 4 representing 4 from 20 =16 and 9 representing the proportion.
