The fumber of heads in 100 tosses of a coin The amount of rain during the next The time takes to drive to the arport The umber of days until your birthday The height of a randamly chosen college student Continuous m. number of songs on a randomly chosen, pod The number of people in hne the bank at a ran Thie weight ofrardornly dosen student's backpack Question 2 (1.1 points) Fill in the missing value so that the following table represents a probability distribution. Write only a number as your answer Your Answer: Question 3 (1.1 points) The federal government has enacted maximum allowable standards for air pollutants such as ozone. Let X be the number of days per year that the level of air pollution exceeds the standard in a certain city. The probability distribution of X is given by Find the probability that the standard is exceeded on at least one day. Write only a number as your answer. Round to two decimal places (for example: 0.53). Do not write as a percentage. Your Answer:

Explanation / Answer

1)

a) discrete

b)continuous

c)continuous

d)discrete

e)continuous

f)continuous

g)discrete

h)discrete

i)continuous

j)discrete

2)for sum of probability =1

hence probability =1-0.31-0.27-0.06 =0.36

3)

here probability that exceed at least one day =1-P(X=0) =1-0.33 =0.67
