In baseball, a player pitches a ball from the mound to a catcher behind the plate. a pitch that passes over the plate above the batter’s knees and below his chest is a strike. all other pitches are “balls,” provided the batter does not swing at them or hit them foul. the table below breaks a sample number of pitches into strikes and balls over the plate and not over the plate. over plate (event c) not over plate (event d) strike (event a) 10 0 ball (event b) 5 20 which conditional probability below is either inaccurately described or inaccurately calculated? the probability that a pitch not over the plate is a strike is zero. so, p(a | d) = 0. the probability that a pitch not over the plate is a ball is 1. so, p(b | d) = 1. the probability that a pitch over the plate is a strike is 10: 15. so, the probability that a pitch over the plate is a ball is 5: 10. so, p(b | c) = 0.5.

Option: D is inaccurately calculated.

( The probability that a pitch over the plate is a ball is 5:10. So, P(B | C) = 0.5 )

Step-by-step explanation:

We will calculate each of the options and then observe which of the option is incorrectly calculated.

We are given a table as:

               over the plate (C)       Not over the plate(D)    Total

strike(A)         10                                0                                10

Ball(B)            5                                 20                              25

Total               15                               20                               35

We know that:

Now:

1)

From the table we have:

Hence, P(A|D)=0.

Hence, option 1 is correct.

2)

Now:

from the table we have:

P(B∩D)=20=P(D)

Hence, P(B|D)=0.

Hence, option 2 is correct.

3)

Now:

from the table we have:

P(A∩C)=10 and P(C)=15

Hence, P(A|C)= 10/15.

Hence, option 3 is correct.

4)

from the table we have:

P(B∩C)=5 and P(C)=15.

Hence, P(B|C)=5/15=1/3.

Hence, option 4 is incorrectly calculated.

Hence, the answer is:

( The probability that a pitch over the plate is a ball is 5:10. So, P(B|C) = 0.5 ).
