From a box containing 10 cards numbered 1 to 10, four cards are drawn together. The probability that their sum is even is 21 21
ankoles [38]

Answer:

Step-by-step explanation:

We know that between 1 to 10 there are 5 even and 5 odd numbers.

We could get 4 even cards , 4 odd cards or 2 odd and 2 even cards

Let´s check all this combinations

Case 1: When all 4 numbers are even:  

We are going to take 4 of the 5 even numbers in the box so we have

5C4=5

Case 2: When all 4 numbers are odd:  

We are going to take 4 of the 5 odd numbers in the box, so we have

5C4=5

Case 3: When 2 are even and 2 are odd:

We are giong to take 2 from 5 even and odd cards in the box so we have

 

5C2 * 5C2

Remember that we obtain the probability from

\frac{Number-of-favourable-Outcome}{Total-number-of-outcomes}

So we have the number of favourable outcomes but we need the Total cases for drawing four cards, so we have that:  

We are taking 4 of the 10 cards:

10C_4=210

Hence we have that the probability that their sum is even

\frac{5+5+100}{210}=\frac{11}{21}

Zach read a book for 10 minutes every weekend in the first month, 20 minutes in the second month, 40 minutes in the third month,
Ray Of Light [21]

Answer:

B) Victoria's method is linear because the number of minutes increased by an equal number every month.

Step-by-step explanation:

Zach reading time written in sequence form is given as:

  • 10,20,40,80,...
  • Each succeeding term is a product of the previous term by 2

Victoria reading time written in sequence form is given as

  • 35,50,65,80...
  • Each succeeding term is an addition of 15 Minutes to the previous term.

The statement that best describes the methods used by Zach and Victoria to increase the time they spent reading a book is therefore:

B) Victoria's method is linear because the number of minutes increased by an equal number every month.
