Fred and his family went to the zoo. fred started the day with $100. he bought 2 adult tickets for
$15 each and 3 kid tickets for $8 each. he then spent half of his remaining money at the zoo gift
shop. the expression below can be used to determine how much money fred had at the end of the
day.

(100 -2 x15 -3x 8) divide 2

23

Step-by-step explanation:

100-(2)15=70

70-(3)8=46

46/2 =23

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

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
