The likelihood that an event will occur given that another event has already occurred

P(A/B) is called the CONDITIONAL PROBABILITY of occurring of event A when event B has already taken place.

Step-by-step explanation:

Let us assume there are two given events A and B.

The probability of A when B has occurred is given as P (A/B).

The probability of B when A has occurred is given as P (B/A)

Also, the probability of occurring A independently  = P(A)

The probability of occurring B independently  = P(B)

Now, the BAYES THEOREM gives us the exact formula to determine the CONDITIONAL PROBABILITY.

By Bayes Formula:

Here, P(A/B) is called the CONDITIONAL PROBABILITY of occurring of event A when event B has already taken place.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
