Answer:
The probability that five cars will arrive during the next thirty minute interval is 0.0127.
Step-by-step explanation:
Let <em>X</em> = number of cars arriving at Sami Schmitt's Scrub and Shine Car Wash.
The average number of cars arriving in 20 minutes is, 8.
The average number of cars arriving in 1 minute is,
.
The average number of cars arriving in 30 minutes is,
.
The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 12.
The probability mass function of <em>X</em> is:

Compute the probability that 5 cars will arrive in 30 minutes as follows:



Thus, the probability that five cars will arrive during the next thirty minute interval is 0.0127.
If you make both of the denominators the same this can be a lot simpler.
1 1/2 divided by 1/4
1 2/4 divided by 1/4
6/4 divided by 1/4
How many times does 1/4 go into 6/4?

Answer: x(0.55)
Step-by-step explanation:
Because 45% of the price is being taking, off we are still paying for 55% of the market price, because 100%-45%=55%.
55/100=0.55
So the sale price is x(0.55)

This situation is a "union." To answer it, add together the probabilities 0.42 and 0.38. Result: 0.80.
The probability of getting into either USC or VSU is 0.80.
