Question

Find P(C|Y) from the information in the table.

A 5-column table has 4 rows. The first column has entries A, B, C, Total. The second column is labeled X with entries 32, 6, 18, 56. The third column is labeled Y with entries 10, 5, 15, 30. The fourth column is labeled Z with entries 28, 25, 7, 60. The fifth column is labeled Total with entries 70, 36, 40, 146.

To the nearest tenth, what is the value of P(C|Y)?

0.4
0.5
0.7
0.8

Answer 1

Answer:

0.5

Step-by-step explanation:

P(C|Y) = P(C^Y)/P(Y)

= 15/30

= 0.5

Answer 2

Using it's concept, it is found that the probability P(C|Y) is given by: 0.5 = 50%.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, Y has 10 + 5 + 15 = 30 outcomes, out of which 15 are C, hence the desired probability is given by:

P(C|Y) = 15/30 = 0.5.
