You reach into a bag of coins and withdraw two coins without replacement. what is the probability you will withdraw a nickel and then a dime if the bag has 5 pennies, ten nickels and four dimes?

The answer is 11.69%.

Step-by-step explanation: Given that there is a bag full of coins, in which

Number of pennies = 5,

number of nickels = 10

and number of dimes = 4.

Therefore, total number of coins in the bag = 5 + 10 + 4 =19.

According to the question, first we draw a nickel, so probability will be

and then, without replacement, we draw a dime, so probability will be

So, the required probability will be

Thus, the probability is 11.69%.

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
