Question

below is a breakdown of student responses to whether they approve of the current healthcare system

	yes	no	unsure
men	40	35	28
woman	68	41	34

Find Each Probability

a. P(yes)

b. P(Men & Unsure)

c. P(Woman or No)

d. P(Unsure/Man)

e.P(Man/Unsure

f.P(Yes or Unsure)

g. P(No or Man)

h. If 2 people are selected, find the probability that they both said no.

Answer 1

(Since there are more than 4 parts i will answer first 4 as per policy)

total no. of responses = 40+35+28+68+41+34 = 246

a.

P(yes) = (total no. of responses "yes")/(total no. of responses)

= (40+68)/ 246

= 108/246

= 0.4390

P(yes) = 0.4390

b.

P(men , unsure) = (total no. of men responding "unsure")/(total no. of responses)

= 28/246

= 0.1138 u

P(men , unsure) = 0.1626

c.

P(woman or no) = (total responses by woman or that are no)/(total no. of responses)

= (68+41+34+35)/246

= 0.7236

P(woman or no) = 0.7236

d.

P(unsure / man) = (total no. of men responding "unsure")/(total no. of responses by men)

= 28/(40+35+28)

= 0.2718

P(unsure / man) = 0.2718
