Answer:  The race lasted for 7452 seconds.

Step-by-step explanation:  Given that a car race lasted 2.07 hours.

We are to find the number of seconds for which the race lasts.

We know that

1 hour = 60 minutes = 60 × 60 seconds = 3600 seconds.

So,

2.07~\textup{hours}=2.07\times 3600~\textup{seconds}\\\\\Rightarrow 2.07~\textup{hours}=7452~\textup{seconds}.

Thus, the race lasted for 7452 seconds.

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}
