What is the sum of the first 15 positive integers?
The sum of the squares of the first 15 positive integers is equal to 1240.
What is the probability of the sum of two numbers being even?
Thus, we have P(even sum)=1/2(P(first was even)+P(first was odd))=1/2(1)=1/2.
What is the probability that their product is even?
The probability that their product is even is. From the first 20 integers, 10 integers should be odd and 10 integers should be even. We know that the product of 3 integers will be even, if atleast one of the integers is even. Therefore, the required probability = 1- Probability that the none of the integers is even.
Is 15 a integer number?
The integers are the set of whole numbers and their opposites. Fractions and decimals are not included in the set of integers. For example, 2,5,0,−12,244,−15 and 8 are all integers.
What are the natural numbers upto 15?
The natural numbers from 1 to 100 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73.
Why do 2 odds make an even?
An even number by definition has no remainder when divided by two. So adding it to another even number will still generate no remainder. Hence an even result.
How do you show that the sum of any two odd integers is even?
The sum of two odd integers is even. Proof: If m and n are odd integers then there exists integers a,b such that m = 2a+1 and n = 2b+1. m + n = 2a+1+2b+1 = 2(a+b+1).
What is the sum of first 20 positive integers?
Answer: The sum of first 20 positive integers will be 210.
What is the probability of the Blue Ball being picked first?
The probability of choosing the blue ball is 2/10 and the probability of choosing the green ball is 3/9 because after the first ball is taken out, there are 9 balls remaining. So the probability is: 2/10 x 3/9 = 6/90 or 1/15 = 6.7\% (Compare that with replacement of 6/100 or 6\%) House of cards activity using probability without replacement
What is the probability of picking a red ball in blackjack?
probability Basics 1 There are 4 red balls in the box so the probability of picking a red ball is 4 out of 10 or 4/10 which can be… 2 There is only one black ball in the box so the probability is 1/10 or 10\%. 3 There are 8 balls that are not blue, so the probability of picking a ball that’s not blue is 8/10 or 80\%. This makes… More
What is the probability of drawing all 3 red cards?
The probability of drawing all 3 red cards can be found by multiplying their probabilities together. This gives 3/7 x 2/6 x 1/5 = 6/210 or 3\% Powered by Create your own unique website with customizable templates.
How do you respond to the probability line above?
Choose an appropriate response from the probability line above for the following events: Some of the events might fall between the probabilities e.g. very unlikely or almost certain. Some responses might depend your own circumstances. For example, find the probability of obtaining Heads from a coin flip.
