If we toss three coins 240 times, how many times can we expect the coins to have three tails showing?
Easy. Use 100 5-cent coins.
This is only possible if you allow adding coinsNumber of coins in row x Number of rows = total number of coins5 x 2 = 10 coins4 x 4 = 20 coinsYou would need 10 more coins
Number of different sums of money that can person form is 15. Step-by-step explanation: Given : A person has 4 coins each of different denomination. To find : What is the number of different sums of money the person can form? Solution : A person has 4 coins each of different denomination. Selecting 1 coin out of 4 coins gives possible ways. Selecting 2 coin out of 4 coins gives possible ways. Selecting 3 coin out of 4 coins gives possible ways. Selecting 4 coin out of 4 coins gives possible ways. Total number of different sums of money that can person form is 4c1+4c2+4c3+4c4= 4+6+4+1=15 Therefore, Number of different sums of money that can person form is 15
To determine the smallest number of coins that will total exactly 17.85, we need to consider the denominations of the coins available. If we have coins in denominations of 0.01, 0.05, 0.10, 0.25, 1.00, and 2.00, we can use a combination of these coins to reach 17.85. The smallest number of coins needed would be achieved by using the highest denomination coins first, followed by the smaller denominations to make up the difference. The specific combination of coins would depend on the availability of each denomination and the constraints of the problem.
The expected number is 3750.
No matter how many coins are thrown, the possibility of having AT LEAST ONE 'head' is 50%. This changes if you specify the number of 'heads' that must be shown.
It is 0.00540 approx.
It depends on the currency.Current US coins are limited to $1 so the number of coins to reach $19.95 will be 24. Nineteen $1 coins, three quarters and two dimes.In times gone by, US currency included $10 and $5 coins so the number was once lower than the current 24 coins.UK currency has a £2 coin so £19.95 will require 14 coins. Nine £2 coins, one £1 coin, one 50 pence, two 20 pence coins and a 5 pence coin.
