The probability that the contestant wins at least one car is 3/5.

<h3>What is the probability?</h3>

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

For 1 car, we consider two possible outcomes:

P(1 car) = 2/6 x 4/5 + 4/6 x 2/5

P(1 car) = 8/15

For no car in either door

P(no car) = 4/6 x 3/5

P(no car) = 2/5

The probability that the contestant wins at least one car is the sum of the probability of one car and the probability of two cars:

P(2 cars) = 2/6 x 1/5

= 1/15

P(1 car) + P(2 cars) = 8/15 + 1/15

= 3/5

A coin is tossed and a spinner numbered 1 to 7 is spun. What is the probability of getting an odd number and heads
Vikki [24]
Your answer is 4/14 or 2/7. There are two possibilities when you flip a coin, heads or tails. Then for the spinner there are 7. Multiply them by each other to get the total number of outcomes of the situation of 14. Then there are only 4 odd numbers from 1-7. This means that you would only be able to get an odd number and heads 4 times.

Hope this helped!

Slater’s room is 5 meter long and 3 1/4 meters wide. What is the area of slader’s room?
muminat
I am guessing it is a rectangular room...
so a 5 x 3 1/4 meter room

The area of a rectangle is length * width
A = l * w
plug in the known
A = 5 * 3 1/4
A = 16.25, or 16 1/4

The area of Slater's?, or Slader's?, room is 16.25 meters^2

Hope this helps
