there is a puarter, three dimes, and two nickels in a bag determan the probability of not picking out a dime or a nickel
To find the probability of not picking out a dime or a nickel, we need to determine the total number of coins in the bag and subtract the number of dimes and nickels.
Total number of coins in the bag = 1 quarter + 3 dimes + 2 nickels = 1 + 3 + 2 = 6
Number of dimes = 3
Number of nickels = 2
Number of coins that are dimes or nickels = 3 + 2 = 5
Number of coins that are neither a dime nor a nickel = Total number of coins in the bag - Number of coins that are dimes or nickels
= 6 - 5
= 1
Therefore, the probability of not picking out a dime or a nickel is 1 out of 6, which can be written as 1/6.
what is the probability of rolling an even or lower than 4
To find the probability of rolling an even or a number lower than 4 on a fair six-sided die, we need to consider the possible outcomes.
There are six possible outcomes when rolling a fair six-sided die: 1, 2, 3, 4, 5, and 6.
Out of these six outcomes, the numbers that are even or lower than 4 are: 1, 2, and 3.
Therefore, the favorable outcomes are 1, 2, and 3, and the total number of possible outcomes is 6.
The probability of rolling an even or a number lower than 4 is the ratio of favorable outcomes to the total number of outcomes:
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 3 / 6
Probability = 1/2
So, the probability of rolling an even or a number lower than 4 is 1/2 or 0.5.
10/5 mile in every 1/10 hour
To find the speed in miles per hour, we need to divide the distance traveled by the time taken.
Distance traveled = 10/5 mile
Time taken = 1/10 hour
Speed = Distance / Time
Speed = (10/5 mile) / (1/10 hour)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
Speed = (10/5 mile) * (10/1 hour)
Speed = (10 * 10) / (5 * 1) mile/hour
Speed = 100 / 5 mile/hour
Speed = 20 miles/hour
Therefore, the speed is 20 miles per hour.
