The probability notation for the probability of choosing a green marble is P(G)
<h3>What is probability?</h3>
This is simply defined as the extent to which something is likely to occur.
The probability that an event will occur is given as the ratio of the number of favorable outcomes to the total number of outcomes.
<h3>How to determine the probability notation</h3>
Probability notation is a symbol used in indicating the probability of an occurring event. Since our focus is on the probability of obtaining a green marble, then the probability notation will be P(G). This is illustrated below:
- Event of green marble = nG
- Total event = nT
- Probability of green marble = P(G)
P(G) = nG / nT

The equation for this is .09x=.34
so just divide .34 by .09
and get X=3.77 repeating
Hope this helps! :D

Answer:
3 hours
Step-by-step explanation:
Distance between South Central High and Redding = 480km
Distance= Average Speed X Time
Let the speed of the express train=x
Let the time taken BG the train=t
For the train:
480=xt...(1)
Since the plane flies 40km/hr faster
Speed of the Plane=x+40
They can save one hour using the plane, so Time taken by the plane
=(t-1)hours
For the plane:
Distance= Average Speed X Time
480=(x+40)(t-1)....(2)
Equate equations 1 and 2 since the distances are equal.
xt=(x+40)(t-1)
xt=xt-x+40t-40
x=40t-40
Substitute x=40t-40 into equation (1)
480=xt
480=(40t-40)t
40t²-40t-480=0
Dividing all through by 40
t²-t-12=0
t²-4t+3t-12=0
t(t-4)+3(t-4)=0
(t-4)(t+3)=0
t-4=0 or t+3=0
t= 4hours (Since t cannot be negative)
Since it will take (t-1) hours to fly, it takes 3 hours to fly to Redding.
