You roll two number cubes let event a = the bumber rolled on the first cube js 6 let event b = the sum of the mubers rolled is 11

D

Step-by-step explanation:

Let A and B be two events as shown in the picture.

We have to say which one we want, and use the symbol "|" to mean "given":

Notion B|A means "Event B given Event A"

In other words, the probability Pr(B|A) says "event A has already happened, now what is the chance of event B?"

P(B|A) is also called the "Conditional Probability" of B given A.

In your case, the probability Pr(B|A) represents "the probability that the sum is 11, given that the first cube shows the number 6".

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
