Anit [1.1K]

Answer:

\frac{10}{-1}

slope = \frac{rise}{run}

\frac{y_{2 - y_{1} } }{x_{2} - x_{3}  } = \frac{60 - 30}{3 - 6} = \frac{30}{-3}

simplify:

A television game show has 12 ​doors, of which the contestant must pick 3. Behind 3 of the doors are expensive​ cars, and behind
almond37 [142]

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
