Stephannie has 60 tickets to use at the carnavial. she used 3/4 of her 60 tickets to play games. then she use 1/5 of her remaining tickets for rides. next she gave half of her remai ning tickets to her brother. how many tickets dis stephanie give to her brother

B=6

Step-by-step explanation:

3/4 of 60 = 45 so 1/4 of 60 equals 15 take that to 1/5 of 15 = 12 divide that in half to get 6 so she gave her brother 6 tickets

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

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
