Andre picks a block out of a bag 60 times and notes that 43 of them were green.

What should Andre estimate for the probability of picking out a green block from this bag?

Mai looks in the bag and sees that there are 6 blocks in the bag. Should Andre change his estimate based on this information? If so, what should the new estimate be? If not, explain your reasoning.

The probability of picking out a green block is 43/60.

Andre shall not change his estimate based on this information because only the number of blocks left are told but the color of the blocks are still unknown. If those blocks are not green, then there is no need to change the estimate.

<u>Explanation:</u>

Probability is a numerical portrayal of how likely an occasion is to happen or how likely it is that a recommendation is valid. Likelihood is a number somewhere in the range of 0 and 1, where, generally, 0 demonstrates inconceivability and 1 shows sureness.

To calculate the probability, divide the number of events with the possible outcomes. This will give us the likelihood of a solitary occasion happening. On account of rolling a 3 on a bite the dust, the quantity of occasions is 1 (there's just a solitary 3 on each kick the bucket), and the quantity of results is 6.

Ben's age is currently twice of his sister, Emma. 8 years ago, Ben's age was 2 and a half times that of Emma's age at that time.
Yakvenalex [24]

Emma is now 24 years old then Ben would be 2E, or 48 years old.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let B and E be Ben's and Emma's current ages, respectively.

We have given that;

Ben's age is currently twice of his sister, Emma.

B = 2E

and

8 years ago, Ben's age was 2 and a half times that of Emma's age

B-8 = 2.5(E-8)      

We can substitute the value of B from the first equation into the last one

B-8 = 2.5(E-8)

(2E)-8 = 2.5(E-8)

2E-8 = 2.5E- 20

-0.5E = -12

E = 24

Thus, Emma is now 24 years old then Ben would be 2E, or 48 years old.
