Question

Any help I rlly don’t get this and I need help

Answer 1

The number of favorable outcomes is the the number of the outcome she wants. She wants a silver car. In her table, 36 cars are silver.
a. 36

The total number of trials is the sum of the all numbers of cars.
12 + 9 + 32 + 42 + 36 + 1
b. 132

The experimental probability of an event is the number of desired outcomes divided by the total number of outcomes.
c. p(silver car) = 36/132 = 3/11

d.
An event takes place, and there are only two possible outcomes.
If the probability of one event happening is x, then the probability of the other event happening is 1 - x.

Think of this situation as only two possible outcomes.
Either a silver car passes or a non-silver car passes.
The probability of a silver car passing is 3/11.
Then the probability of a non-silver car passing is 1 - 3/11.
1 - 3/11 = 11/11 - 3/11 = 8/11
