35

3591.7

3591.760

Explanation:

Horizontally the table values total the

number in the first column.

first row missing table value = 700-665

second row missing table values = 300

-240 60

35

The conditional probability formula

applies.

P(contains I positive) = P(contains &

positive)/P(positive)

The probability associated with each

table entry is that value divided by 1000.

Then the numbers in the formula are ..

.665/.725 91.7%

P(contains I positive) = 665/(665+.060)

Answer 2

Answer:

• 35
• 60
• 91.7

Explanation:

Horizontally the table values total the number in the first column.

first row missing table value = 700 -665 = 35

second row missing table values = 300 -240 = 60

__

The conditional probability formula applies.

P(contains | positive) = P(contains & positive)/P(positive)

The probability associated with each table entry is that value divided by 1000. Then the numbers in the formula are ...

P(contains | positive) = .665/(.665+.060) = .665/.725 ≈ 91.7%
