A gumball machine is filled randomly with gumballs:red,green,purple,white,pink and yellow. The company claims the following percentages of each can be found in an unopened carton.30%red,20%green,20%purple ,20% white,5%pink and 5%yellow. What is the probability that the first gumball to come out of the machine is either red or white.(Give answer as a percentage).
Half the gumballs in the machine are either red or white, so 50%
To find the probability of getting either a red or white gumball as the first one out of the machine, we need to calculate the sum of the individual probabilities of getting each color.
First, let's calculate the probability of getting a red gumball:
The company claims that 30% of the gumballs in an unopened carton are red. Therefore, the probability of getting a red gumball is 30%.
Next, let's calculate the probability of getting a white gumball:
The company claims that 20% of the gumballs in an unopened carton are white. Therefore, the probability of getting a white gumball is 20%.
Now, we can find the probability of getting either a red or white gumball:
P(red or white) = P(red) + P(white)
= 30% + 20%
= 50%
Therefore, the probability that the first gumball to come out of the machine is either red or white is 50%.
