In car racing competition, four car brands A, B, C, and D are competing with two cars each. Each of the cars from A, B, C have the same chance of winning, while each of D’s cars have twice the chance of winning. What is the probability of winning for the D brand?

P(D)=2/5

Step-by-step explanation:

We know that in car racing competition, four car brands A, B, C, and D are competing with two cars each. Each of the cars from A, B, C have the same chance of winning, while each of D’s cars have twice the chance of winning. We get

We conclude that the probability of winning for the D brand is

2.
