HELP PLEASE ME WITH BOTH OF THESE

0.9  3/4  and 15/3

Hope this helps :D

and what do you mean by BOTH of there?

there is only one question

0.90, 3/4, and im not sure about 15/3

Step-by-step explanation:

0.45 = 45% so anything above 0.45 is correct. 0.400 and 0.40 are less than 45%

3/4 would be 75% so that is greater

hope i helped a bit!!

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
