a + 20 = 84 (calculated 7*12)

a = 84 - 20 (subtracted 20 on both sides)

a = 64 (calculated 84-20)

sergey [27]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Upper P (Upper B vertical line Upper A)

means

$P(B|A)$

It means that probability of getting event B given that Event A is occurred.

D. The probability of event B occurring, given that event A has already occurred. is also expressed as $P(B|A)$

Hence, Option 'D' is correct.
