The probability of first drawing a blue one, and then a green one, is:

P = 0.19

<h3>How to get the probability?</h3>

There is a total of 13 marbles, such that:

  • 6 are blue.
  • 2 are green.
  • 5 are red.

Now we draw two marbles, we want to get the probability that the first one is blue, this is equal to the quotient between the number of blue balls and the total number of balls.

p₁ = 6/13

Now, after that, we want to draw a green one. The probability is computed in the same way (notice that now there are 12 marbles).

p₂ = 5/12

Finally, the joint probability is the product of these two:

P = (6/13)*(5/12) = 0.19

Describe a real-life multiplication situation for which an estimate makes sense . Explain why it makes sense
monitta

Answer: Here we have a real life multiplication situation for which an estimate make sense:-


Miley has 212 fiction books. Sharon has 3 times fiction books has many as Miley has, how many fiction books Sharon has

Solution :- Number of fiction books Miley has = 212

Number of fiction books Sharon has= 3 times 212

We know that 212 is near to 200 , so round off 212 to 200 (to the nearest hundred)

Thus the product becomes 3\times200=600

Therefore, the estimated number of fiction books Sharon has=600
