A boat travelled 6km upstream at X km/h. How long did the journey take? When returning downstream, the speed of the boat was 2X km/h. How long did the return journey take? If the downstream journey took 15 min less than the upstream journey, form an equation for X and solve it.

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

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
