Help binomial distributions
Ymorist [56]

We have the formula to compute the probability of having exactly k successed over n trials, given a probability p of success (and implicitly a probability 1-p of failure), which is


P(\text{k successed on n trials}) = \binom{n}{k}p^k(1-p)^{n-k}


Now, the probability of at least 3 successes is the union of the following event: exactly three successes,exactly four successes and exactly five successes.


We can compute their probability and sum them:\binom{5}{3}\left(\frac{3}{7}\right)^3\left(\frac{4}{7}\right)^2 + \binom{5}{4}\left(\frac{3}{7}\right)^4\left(\frac{4}{7}\right)^1 + \binom{5}{5}\left(\frac{3}{7}\right)^5 \approx 0.36788


So, the answer is about 36.79%

Which form of money came into existence because of goldsmiths receipts?
AveGali [126]
<span>PAPER MONEY.
As wealth increases, owning a large number of gold and silver coins becomes a security problem. As coins are portable, they are also easy to steal. The next step in the development of money was for people to leave their surplus gold and silver coins with a goldsmith who had a reputation for honesty and who operated premises which were secure. The goldsmith would give a receipt, which would entitle the owner to withdraw their coins when they needed them. This was the beginning of paper money.</span>
