Answer:

Step-by-step explanation:
To evaluate f(4) substitute x = 4 into f(x)
f(4) = 5 ×
= 5 ×
= 
(a) 1A 2A 3A 1B 2B 3B (6 possible outcomes
(b) Possible outcomes for A or 1 are 1A 2A 3A and 1B ( 4 outcomes) therefore:
Probabilty = 4/6 = 2/3
That is in standard form except the -7 would be written as a power next to the 10. As an ordinary number it is 0.000000475
Answer:
