What is the probability of rolling an odd number or an even number on a cube?
To answer this problem you first see how many even and odd numbers there are. There are 3 odd and 3 even. so the fraction for even and odd is 3/6 so then in simplified form it is 1/2. If they ask to express the probability as a decimal number it would be .5 or.50
What does even and odd mean?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2.
Integers a b c and d not necessarily distinct are chosen independently and at random from 0 to 2007 inclusive What is the probability that ad-bc is even?
10/16 = .625 Analysis: a and d will be odd if and only if both are odd. Therefor, ad will be odd 1/4 the time. The same goes for bc. It will be odd 1/4 off the time. ad-bc is even if and only if both ad and bc are either odd or even. It's easiest to solve it from here with a table: ad bc ad-bc prob even even even 3/4*3/4 = 9/16 even odd odd 3/4*1/4 = 3/16 odd even odd 1/4*3/4 = 3/16 odd odd even 1/4*1/4 = 1/16 So, ad-bc will be even 9/16+1/16 = 10/16 of the time.
What is the probability of rolling an odd number on 1 roll of die?
With a single die:There are 6 sides on a dice.There are 3 sides that are odd (1, 3, 5)3/6 = 1/2 = 50%Therefore, a single die has a 50% chance of landing on an odd number.If you have two dice:I'll explain this the longer way, however there are short (and simpler explanations) that basically use the fact that a single die is 50%, therefore two independent dice will also be 50%.Number of dice = 2Sides of a dice = 6Odd sides: 1, 3, 5, so Number of odd sides on a dice = 3Even sides: 2, 4, 6, so Number of even sides = 3Total combinations with two 6 sided dice = (sides on dice x sides on dice) = 6 x 6 = 36We need to take the fact that:An odd number + an odd number = evenAn even number + an even number = evenAn odd number + an even number = odd
What is the probability of choosing odd number?
If you chose the number out of an equal numberof odd and even numbers then it would be 50% chance. Like if you chose an odd number out of the numbers from 1 to 100
Is the number 225 even or odd?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 225 is an odd number.
Is 225 an even number?
No, it is odd
Is 225 a multiple of 14?
No. All multiples of 14 are even; 225 is an odd number; therefore it cannot be a multiple of 14.
If you add 3 to an even number the sum would be odd or even?
Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
Does multiplying an odd number by an even number give an even answer?
odd * odd = odd answer even * even = even answer odd * even = even answer
Is even times even odd?
even times even = even odd times even = even odd times odd = odd
What is the sum of the first 15 odd number?
225
When you add to even numbers is the answer always even?
Yes. Even + Even = Even, Odd + Odd = Even and Even + Odd or Odd + Even = Odd
Is the sum of an odd number and an even number always even?
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
What is the sum of the first fifteen odd numbers?
The sum of the first 15 odd numbers is 225.
What happens when you add two even numbers Will you get an even number?
Always. even + even = even odd + odd = even even + odd = odd odd + even = odd To summarise, if you add like numbers you get even, otherwise you get odd.
Is even times even?
even times even = even odd times even = even odd times odd = odd
