Given:
No of users in February is 45,000 and in october its 60,000.

t=2




Therefore, approximate no of users after 2 years is 106667.
The bag contains,
Red (R) marbles is 9, Green (G) marbles is 7 and Blue (B) marbles is 4,
Total marbles (possible outcome) is,

Let P(R) represent the probablity of picking a red marble,
P(G) represent the probability of picking a green marble and,
P(B) represent the probability of picking a blue marble.
Probability , P, is,


Probablity of drawing a Red marble (R) and then a blue marble (B) without being replaced,
That means once a marble is drawn, the total marbles (possible outcome) reduces as well,

Hence, the best option is G.
Answer:
(b) 2.71828 . . .
Step-by-step explanation:
If your calculator does not have an 'e' button, you can have it compute e^1 using the exponential function button.
