Mildred has a bag of coins the back contains 10 dimes five Nichols and one penny to randomly select two coins from the bad one at a time with the replacement what is the probability that Mildred Will select the dime first then a penny
I think someone should check their math before correcting other people's grammar. 1/24 is correct and 5/128 is incorrect. This is a STAAR released question from 2015. It has an answer key. You don't put the penny back!
A 5 cent coin is called a nickel not a Nichol.
10 dimes
5 nickels
1 penny
Prob(dime, then penny)
= (10/16)(1/16)
= 5/128
I recommend that you check your typing, spelling, and grammar in any future posting.
e.g.
bag --> back -->bad
10/16 * 1/15 = 1/24
Heyy Bob how did you get 1/24 sorry it's because I have a test and it asked this quetion and I just wanna now how did you get this answer
Welll ion know I have a test and try to figure this out so is it 5/128 or 1/24?
Marlena has a bag of coins. The bag contains 8 quarters, 10 dimes, 4 nickels, and 2 pennies. She will randomly select a coin from the bag. What is the probability that Marlena will select a nickel?
To find the probability of selecting a dime first, and then a penny, we need to calculate the probability of each event occurring separately and then multiply them together.
1. Probability of selecting a dime first:
Since there are a total of 10 dimes in the bag, out of a total of 10 + 5 + 1 = 16 coins, the probability of selecting a dime first is:
P(dime first) = Number of dimes / Total number of coins
= 10/16
= 5/8
2. Probability of selecting a penny:
After replacing the first coin back in the bag, there will still be a total of 10 dimes, 5 nickels, and 1 penny. Hence, the probability of selecting a penny second is:
P(penny second) = Number of pennies / Total number of coins
= 1/16
Now, to find the probability of both events happening, we multiply the probabilities together:
P(dime first and penny second) = P(dime first) * P(penny second)
= (5/8) * (1/16)
= 5/128
Therefore, the probability that Mildred will select a dime first, and then a penny, is 5/128.
