61/3 ÷ 6 10/3 simplify the expression

6 1/3

6 10/3 = 9 1/3

9 1/3 divided by 6 1/3 = 1.47368421053

6 1/3 ÷ 6 10/3  Both the 6 get cancelled.  1/3 ÷ 10/3  1/3 × 3/10  3/30 = 1/10

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
