Nicholas borrowed $500 for 2 years at a 10% interest rate. How much interest will he pay on the loan ?

He will repay $100

Step-by-step explanation: The interest payable after a given number of years is calculated by the following formula;

Interest = PRT

Where P is the initial amount invested/borrowed, R is the rate of interest payable (in percentage) and T is the time in years.

Substituting values into the formulae, we now have;

Interest = 500 x (10/100) x 2

Interest = 1000 x 0.1

Interest = 100

Therefore the interest payable is $100

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
