Abag contains 4 blue balls, 7 yellow balls and 4 white balls. event a is defined as drawing a blue ball on the first draw and event b is defined as
drawing a white ball on the second draw. if two balls are drawn from the bag, one after the other and not replaced,
what is p(b|a) expressed in simplest form?

4/14 or 29%

Step-by-step explanation:

So p(B|A) basically means that we are finding the probability of b now that a has already happened.

In this scenario once a has happened, there are 3 blue balls, 7 yellow, and 4 white so the probability is 4/14 which is approximately 29%

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
