Find the right answer of the following problem
Problem- Jonny is getting bubble gum balls out of a gumball machine. There are equal amounts of red, green, purple and blue gumballs, however there are twice as many orange gumballs in the machine as there are red ones.
Part A- What is the probability of getting a blue gumball on the first try?
Part B- What is the probability of getting an orange gumball.
Part C- Due to the large amount of gumballs in the machine, we will assume that the relative probabilities do not change with the removal of one gumball, what is the probability that Jonny gets two consecutive blue gumballs?
Part D- What is the probability that Jonny gets an orange gumball followed by a blue one?
I want experts help to determine the probability of getting an orange gumball.
