The tree diagram below shows the distribution of cars sold and whether each type got upgrades or not. Find the Probability of a random car getting an upgrade.
To find the probability of a random car getting an upgrade, we need to consider the total number of cars sold and the number of cars that received upgrades.
From the tree diagram, we can see that there are a total of 130 cars sold. Out of those cars, 70 received upgrades.
Therefore, the probability of a random car getting an upgrade is:
Probability = Number of cars with upgrades / Total number of cars sold
Probability = 70 / 130
Probability = 0.5385 or 53.85%
So, the probability of a random car getting an upgrade is 53.85%.
