In probability, you gather data through statistics and from there, determine the chances of how likely an event is going to happen out of the total number of data you've collected. Hence, probability is always expressed as part of a whole. This can be in terms of fraction, decimal or in percentage.

You are given statistics: 12 girls and 16 boys. You solve for the total which is 12+16 = 28. This would be the denominator of your probability. For the numerator, we use the statistics for the girls. Therefore, the probability of selecting a girl to dive first is

Probability = 12/28 = 3/7 or 42.86%

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}
