Answer:

a) 0.6

b) 0.3

Step-by-step explanation:

Since we are taking 3 from a sample of 5 without replacements, we would have 5 choices for the first pick, 4 choices for the 2nd pick and 3 choices for the 3rd pick. The total possible number of ways to do this is:

5*4*3 = 60 ways

As order does not matter (GLS is the same as GSL), we divide this by the number of ways the 3 picks can be arrange, which is 3*2*1 = 6

So there are 60/6 = 10 possible samples

(a) If the governor is included in the sample, then we only have 4 choices for the 2nd pick and 3 choices for the 3rd pick. And there are also 2 ways to arrange this.

So there are 4*3/2 = 6 possible samples. The probability of this happening is 6/10 = 0.6

(b) If G and A are included, we only have 3 choices for the last pick. So the probability of this to happen is 3/10 = 0.3

4(k-2) when it says 2 less than it means you are subtracting from the constant and 4 times means you are multiplying the whole equation with 4.

Answer:

<u>2,365,200,000 times</u>

Step-by-step explanation:

<u>Given</u> :

  • Average heartbeat rate = 60 times/minute
  • Avg. human lifespan = 75 years

<u>To Find</u> :

  • Number of heartbeats in lifetime of 75 years

<u>Solving</u> :

  • Let the number we require be n
  • n = average heartbeat rate x 60 x 24 x 365 x 75
  • n = 60 x 60 x 24 x 365 x 75
  • n = 3600 x 24 x 365 x 75
  • n = 86400 x 365 x 75
  • n = 31536000 x 75
  • n = <u>2,365,200,000 times</u>
