Brandon and jerry like to play video games. brandon has vv video games, and jerry has 2929 video games. together they have a total of 7373 video games.

Brandon has 44 video games.

Step-by-step explanation:

Brandon and Jerry like to play video games.

Brandon has 'v' video games and Jerry has 29 video games.

together they have a total video games = v + 29 = 73

v = 73 - 29

v = 44 video games

Brandon has 44 video games.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
